I will be playing Battlefield 3, Counter-Strike: Global Offensive, Crysis 2, Skyrim at 1920x1080 ultra settings.
If I get the AMD Radeon HD 7970 3GB I have to pay +$21 USD. Is it really worth it?
More aboutradeon 7970
its worth much more than $21 for the performance.
Yes it's worth it. The 7970 in crossfire is better than the GTX580 in SLI. Since you like your graphically intensive games, a year from now when games get even more eye blistering you might want another 7970.
I'm a nvidia fan, and I say: Get the AMD HD7970! Totally worth it
Yes, get it! It is way better, and crossfire is better than sli. It is way better performance and it can play all those games maxed settings plus more. I have one and crossfired it and it is off the charts.
