After playing the Battlefield 2 Demo on my PC (Asus A7V8X-X, AMD Athlon XP 2400+, 1 Gig of Ram and GeForce FX5900 AGP) for a while, I've come to the conclusion I need to upgrade. First of all, if I were to install a 6800GT or X800XL in my rig, would my processor cause a major bottleneck? Second of all, does anyone think I'd be able to run Battlefield 2 on high settings, 1024x768, no AA or AF? I can understand if no one could answer the second question, but I really need an answer for the first and would greatly appreciate any help.
