I asked ChatGPT, Perplexity, and Gemini to build me a gaming PC, and one made a big mistake

A journalist tested ChatGPT, Perplexity, and Gemini by asking each to recommend components for a $2,000 gaming PC build. ChatGPT provided a detailed build with a Ryzen 7 9800X3D bundle and RTX 5070 Ti, while Perplexity suggested a Ryzen 7 7800X3D bundle and RX 7900 XT, but one AI made a significant pricing error. The experiment highlights that AI tools can assist with PC building but require users to verify prices and availability.

That includes shopping and providing relevant information on potential purchases. But can it help save money on sourcing components and reliably support the planning of a PC build? Not always. As a believer in component bundles, I tasked ChatGPT, Perplexity, and Gemini with finding some before filling in the gaps. Here’s what happened. The initial prompt My prompt to all three AI assistants was the same. I wanted to focus on a pretty powerful mid-range system build, and set a $2,000 budget: “I’m trying to build a new gaming PC for up to $2000. Are you able to recommend any component bundles worth looking at, including a CPU and motherboard, from US retailers” Latest PC & Tech deals Acer Predator Helios Neo 16 - was $2,199 now $1,749 ASUS SFF-Ready RTX 5080 - was $1,499 now $1,354 Samsung Odyssey G7- was $999 now $649 HP OMEN 45L gaming PC - was $2,499 now $2,309 BIWIN Black Opal NV7400 4TB SSD - was $599 now $459 Prices correct as of July 10th, 2026. Clear enough, so I hit enter on each and let the tools do their best. The results? Pretty solid to start, with the caveat that you should definitely always check and compare prices. We saw ChatGPT specifically get pricing wrong when asking it to outbuild the Steam Machine. Prices can change quickly and are higher in 2026, so always make sure and don’t take an AI tool’s word on it. ChatGPT’s response For a $2,000 gaming PC, I’d focus on bundles that maximize the value of the CPU + motherboard + RAM, then spend as much as possible on the GPU . The two US retailers I recommend checking first are: Micro Center Bundle Deals Newegg Combo Builder Best overall gaming bundle This would be my first choice if it’s available at your local Micro Center: Ryzen 7 9800X3D + MSI X870E-P Pro WiFi + 32GB Corsair DDR5-6000 Bundle price: $829.99Regular combined price: $1,099.97Savings: About $270 My recommended $2,000 build Component | Recommendation | Approx. Price | |---|---|---| | Bundle | Ryzen 7 9800X3D + X870E + 32GB DDR5 | $830 | GPU | RTX 5070 Ti 16GB | ~$800 | SSD | WD Black SN850X 2TB | ~$150 | Cooler | Thermalright Phantom Spirit 120 SE | ~$40 | PSU | Corsair RM850x ATX 3.1 | ~$140 | Case | Fractal North, Lian Li Lancool 216, or Corsair 4000D Airflow | ~$100 | Estimated total: $1,950–2,000 before tax. That’s a comprehensive response, and it includes the best CPU for gaming https://www.pcguide.com/cpu/guide/best-for-gaming/ . Assuming availability, the savings are solid, and the inclusion of Newegg and Micro Center offers some options for further research. Plus, I was given an immediate estimated total, so we know roughly where we are before tax. Perplexity’s response Yes – the strongest US-retailer bundle option for a $2000 gaming PC is Micro Center’s AMD CPU + motherboard + RAM combo, especially the Ryzen 7 7800X3D bundle. Micro Center also has a broader AMD bundle page, while Newegg and Best Buy have bundle/package sections worth checking if you want alternatives . Bundle | Why it’s worth looking at | Retailer | |---|---|---| Ryzen 7 7800X3D + AM5 motherboard + 32GB DDR5 | Best gaming-value bundle I found, and it leaves more budget for the GPU. wccftech | Micro Center | Other AMD processor + motherboard bundles | Good if the 7800X3D bundle is out of stock or priced higher locally. microcenter | Micro Center | AMD CPU/motherboard combo listings | Useful backup option if you want to compare package pricing. newegg+1 | Newegg | Motherboard & CPU packages | Another US retailer alternative, though usually less compelling than Micro Center for gaming-focused value. bestbuy | Best Buy | Using a $699.99 RX 7900 XT-class card and a $120 case, the total comes to about $1,660.96 before tax. If the GPU is closer to $799.99 and the case is $140, the total is about $1,780.96 before tax Perplexity tried to offer options across retailers but, weirdly, only specified a Micro Center bundle: the Ryzen 7 7800X3D + AM5 motherboard + 32GB DDR5. Not too shabby, as the Ryzen 7 7800X3D is a fine option even if it’s last-gen. I also got extra information about the full spend, depending on GPU and case costs. But it doesn’t go as far as ChatGPT in completing the parts list. Gemini’s response Gemini focused on Micro Center but gave the most detailed response of all, offering up three distinct options. I’ve summarized those below because they are extensive with a capital E, even including an Intel ‘hybrid’ option. Top marks for giving users options, Gemini. Micro Center’s CPU, motherboard, and RAM combinations are a fantastic way to save cash on a $2,000 budget, allowing you to maximize your remaining funds for a top-tier graphics card. The most compelling bundle configurations at Micro Center that align perfectly with your budget include the following: The Ultimate Gaming Standard: AMD Ryzen 7 9850X3D 3-in-1 Bundle - CPU: AMD Ryzen 7 9850X3D with 3D V-Cache - Motherboard: ASUS TUF Gaming B850-E Wifi - RAM: Corsair Vengeance RGB 32GB DDR5-6000Bundle Price: ~$699.99 Saves roughly $370 compared to buying standalone parts The Pure Value King: AMD Ryzen 7 7800X3D Bundle - CPU: AMD Ryzen 7 7800X3D - Motherboard: ASUS ROG Strix B650E-F Gaming WiFi or equivalent B650E Max board - RAM: Corsair Vengeance 32GB DDR5-6000 Bundle Price: ~$599.99 Or ~$399.99 for just the CPU and Motherboard The Balanced Productivity Hybrid: Intel Core Ultra 7 270K Bundle - CPU: Intel Core Ultra 7 270K - Motherboard: MSI Z890 Gaming Plus WiFi - RAM: G.Skill Ripjaws S5 32GB DDR5-6000 Bundle Price: ~$549.99 The full build list ChatGPT was the only AI tool to have replied immediately with a full, recommended build list. So, with a bit of prompting to complete the checklist in the others, here are the three for comparison. Although there is one specific issue here that any PC builder should spot immediately: ChatGPT – full build Component | Recommendation | Approx. Price | |---|---|---| | Bundle | Ryzen 7 9800X3D + X870E + 32GB DDR5 | $830 | GPU | RTX 5070 Ti 16GB | $800 | SSD | WD Black SN850X 2TB | $150 | Cooler | Thermalright Phantom Spirit 120 SE | $40 | PSU | Corsair RM850x ATX 3.1 | $140 | Case | Fractal North, Lian Li Lancool 216, or Corsair 4000D Airflow | $100 | Estimated total: $1,950–2,000 before tax. Kevin’s note | Perplexity – full build | Part | Exact pick | Est. price | |---|---|---| Bundle | AMD Ryzen 7 7800X3D + ASUS B650E-E TUF Gaming WiFi + G.Skill Flare X5 32GB DDR5-6000 bundle | $599.99 | GPU | AMD Radeon RX 7900 XT-class card from Micro Center | $699.99 to $799.99 | PSU | PowerSpec 850W 80 Plus Gold Certified Fully Modular ATX Power Supply | $94.99 | SSD | Inland Premium 2TB SSD M.2 2280 PCIe NVMe 3.0 x4 | $145.99 | Case | Airflow-focused ATX mid-tower case from Micro Center | about $100 to $140 | Estimated total: $1,660.96 before tax Kevin’s note | Gemini – full build | Category | Item Description | Price | |---|---|---| The Core Combo | Ryzen 7 7800X3D + ASUS B650E MB + 32GB DDR5 RAM | $699.99 | Graphics Card | NVIDIA GeForce RTX 4070 Ti Super 16GB | $799.99 | Storage | WD Black SN850X 2TB NVMe M.2 SSD | $149.99 | Power Supply | Corsair RM850e 850W ATX 3.1 Gold | $119.99 | CPU Cooler | Thermalright Peerless Assassin 120 SE | $34.90 | PC Case | Montech AIR 903 MAX Mid-Tower | $75.00 | | | | Estimated total: $1,879.86 before tax Kevin’s note | These are all completely viable builds and, as you’d expect, each AI tool gave a little nod to the cost before tax. However, Gemini went a step further, offering an additional thought on the remaining budget. Where to Use the Leftover ~$120: This setup leaves you comfortably under your absolute $2,000 ceiling. You can hold onto the extra cash to absorb local state sales tax, or reallocate it toward aesthetics—like upgrading the air cooler to a premium Liquid AIO such as the Arctic Liquid Freezer III 360 to completely fill out the top of the Montech case. The big mistake Decent advice, and honestly, it’s somewhat odd that Gemini should mention a CPU cooler. Somehow, inexplicably, that’s precisely what Perplexity completely failed to include in the parts table or anywhere. And I’d call that a major mistake. The Ryzen 7 7800X3D can run hot, and it definitely doesn’t come with a CPU cooler. Not only should one be installed – as with all CPUs – but you’ll need a reliable option to keep it cool. Going further, I’m a little surprised. AI may not get prices exactly right, but omitting a core component from a build on this list is dangerous. I’d hope most people would notice the missing part long before anything gets switched on, and only suffer a biut of delay and frustration. Because a budget is one thing, but replacing a just-bought CPU is not what anyone wants. So, beyond the otherwise fair bundle and component selection, AI is a tool to be used while acknowledging it can and still does make mistakes. Hopefully nothing that causes a CPU to spontaneously melt… but judging by the above, let’s not take it for granted. If you’re using AI for information on builds or CPU parts, be sure to keep your wits about you.
