rtx 4090 + huawei atlas duo for qwen flash next ?

I have rtx 4090 and 64 gb of ddr4 ram. This is enough to fit smaller quants of qfn, but I found them not great and switched back to qwen3.8. However, there are option that bother me a lot, buy huawei atlas duo, thats another 96 gb of ram thats twice faster than system ram and another AI accelerator, thats faster than cpu.

Anybody tried that ?
