So if I sold my 2080 now for £450-£500. Then waited for these new GPU's come out, I could get a 3080 possibly for £600? which would be at least 2080Ti performance.
Or at least get a 3070, but nobody knows if it'll be the same as a 2080Ti, no point doing this if it's the same performance as my 2080 though.
Decisions..
You won’t be doing yourself any harm getting rid of your 20 series gfx card...it was always a stop gap gen... let’s face it RTX was never a thing with this gen...and the 2080 only as fast as the 1080ti that was 3 years old but yet the 2080 cost more...:/
Make a decision sooner or than later though...as once 30 series hits the 2080 will plummet and not hold its own like the 1080ti did and still does...
Lots of people try to time that to perfection, ask @easyrider
It works for me as I game mostly from September onwards...spring summer I’m out and about...
