recommend gpu

Hi all, It's looking like I'll have to replace my GTX 970 in the near future. I'm using a 1440p 60Hz monitor and the only games I'm interested in where the GTX 970 is not fast enough are Metro Exodus (recommended: 2070 or 3070 for Enhanced) and the not-yet-released S.T.A.L.K.E.R. 2...

I was considering upgrading graphic card for my current setup, but I'm not too sure what to get. More specifically, what's the best GPU that I can get that wouldn't completely bottleneck my system? Current Specs: CPU: Ryzen 7 2700 Ram: 16gb ddr4 3000 GPU: Radeon HD 6850 (really old model)...
