Here, I took some time to dig some data from Analitycs. These are the guys reading my website, and they are prety much the enthusiast cream aroung here (GTX 480 SLi, GTX 580 SLI, i980X, etc). Of course, I will not test in 1280x1024 just because more people use that res. But I will not consider 2560x1600 as beeing relevant
for a specific scenario gaming test, when only 0.26% of my readers use that res. And yes, I think that it is very important to use that res
in the launch article for high-end cards. Now, you can say whatever you want, but untill I do not see the same graph from TechpowerUP, Guru3D, Anandtech or any other hardware testing site, this is the crowd I am writing for.
