Since I don't have a 1440p monitor and used 1080s & 2060s are the same price, which one would you recommend ? There's a 70€ difference between those and a new RX 6600 so I'll likely go with NVIDIA here
RX6600 is comfortably stronger than those 2.
GTX1080 has nothing to help it match or beat 6600.
2060 has DLSS to help it.
With RX6600 being stronger and having FSR2.1 or whatever is latest version at its disposale the DLSS would not necesarily help 2060 to win,even if DLSS 2.3 or whichever is typicaly better.
Even if it would,it would be usually be minor difference.
It does tend to have cleaner picture quality vs FSR.
IF you are not into Raytracing or consider it just a nice bonus to just occasionaly use.then RX6600 would be my choice.
IF you are into RT even 2060 is not so terrible as some many claim,especially with DLSS.
In RT department 2060 will beat 6600 with or without DLSS.
Demolish it with DLSS.
Both 1080 and 2060 can use FSR as well as Intel Xess that is also supported by 6600.
Xess is often better than FSR from what I noticed,but in less games for now.
AMD is actively blocking DLSS implementation is AMD sponsored games.
And Xess as well I think.
All in all.I would go with RX6600.
I imagine 2 years Warranty is worth 70 Euros.
Unless you need it for content creation.
Video editing and stuff in Da Vinci resolve.
Then 6600 is not best choice of the 3.
