R9700 and 9070XT, is there a good way of combining them?

A Level1Techs forum user asks whether to keep both an AMD Radeon RX 9070 XT and an AMD Ryzen 9 9700X (R9700) for AI workloads, noting that with llama.cpp split-mode layer they could run models like Qwen3.8-27B-UD-Q4_K_XL with full 256k context, but most advice suggests selling the 9070 XT to recoup costs.

aram https://forum.level1techs.com/u/aram 1 Hi there, I have been playing with a 9070XT until recently, but had some money saving and saw an R9700 at a not completely crazy price in the UK and got it. Now I am wondering if it is worth it to keep both will need a new PSU . Or if I am better off selling the 9070XT to recoup some of my expense. I have had a look around and in Reddit and mostly I get the impression that selling and recouping is my best option, but there’s been enough videos about the R9700 in the youtube channel that I thought “Maybe someone in the forums has a good idea?” with llama.cpp you can use split-mode layer to run models that are 32+16 GB You could fit Qwen3.8-27B-UD-Q4 K XL https://huggingface.co/unsloth/Qwen3.8-27B-GGUF?show file info=Qwen3.8-27B-UD-Q4 K XL.gguf with the full 256k context windows and MTP
