Hey guys, I'm about to choose a GPU for my desktop. I'm stuck between the 6950 or the GTX 560 Ti. Which is better? I've seen opinions that say the 6950 is better, others that GTX 560 ti is better. It's hard to give an opinion without being biased i know. My favourite game atm is starcraft 2 and I'll be playing in Full HD 1920x1080. I have an AMD system (AMD CPU on a 890GX). so what do you think?
