Yeah, I mean, as you say it's really not up to pushing out ray tracing...and i play at 1440p, so that would put it under even more load, wouldn't it?
I'm unsure what to upgrade to, vis a vis a new GPU.
Could my CPU do a 2080 justice?
Would anything from the new 30 series definitely require a new processor, do you think?
Why get a 2080? The 2000 series cards all kinda suck at raytracing to be blunt the 3000 series pulls far far far ahead of them. Also a 2080 costs about as much as a 3080 right now and sure you can't get the 3080 but just wait it's not like a 2060 is a bad card for normal gaming. That and currently raytracing does not do much in games other than oh look these reflections are accurate now compared to oh look those reflections look believable. It does have a good impact on lighting but really in most games it's not that big of an impact with the new consoles coming out we will probably see more of it tho but for now it's very much so a nice to have but not must have feature.
For the cpu. Totally depends 1440p 60fps? No problem. 144+ yeah that will be a lot harder for it.
Anyways tl;dr cpu is fine if you aren't wanting over 144fps and wait for the 3000 series to become available again as the 2000 series are bad for the price.
