What GPUs could I pair with these CPUs and not bottleneck them too badly? That is, I'm technically OK 'bottlenecking' them some, but not to an extent that the upgrade is no longer a good value. I.e. would pairing them with a 3060 be reasonable, or would I be better off with a used 2060 and more modern Ryzen CPU (of course, then I'd need to factor in a new motherboard and RAM - currently have 64GB in these system)? Also, it looks like I can overclock the 1620 to around 4Ghz...
Thanks,
