I am a hardcore gamer and I play most of the latest games. Till now I was using Nvidia graphic cards in my system. Now I think I am planning to change the graphic cards of my system. I am thinking that I will try AT graphic cards for a change. I visited the official website of ATI and was looking for high end graphic cards. During this browsing, ATI Radeon HD 7950 and ATI Radeon HD 7970 caught my attention. I think that these are the graphic cards that will fulfill my needs. Before I buy them, I needed some opinion and views from experienced users. How good are they when compared among themselves? If I need to buy ATI Radeon HD 7950, I will be buying 3 of them and if I need to buy ATI Radeon HD 7970, then Iíll buy 2 of them. Does anyone else use these graphic cards?
