I'm upgrading my aging PC for something that will run my new favorite game, Battlefield 2142, with high settings. I'm looking to spend somewhere around $275 for the graphics card alone and have looked into both nVidia's GeForce 7900GTO and ATi's Radeon X1900XT 256MB card but the question is, which one will give me better performance? Or is the performance close enough that I should just pick whichever one I like more?
