I would like to play at the 1280 resolutions (1280 x 1024, 1280 x 960). I already do play most of my games at that resolution, but usually with Medium settings and no AA. I'm primarily a console gamer (actually, right now I'm primarily a handheld gamer), but the PC has some genres that neither consoles or handhelds are capable of accurately reproducing right now, namely FPS, RTS, and MMORPG games. However, I'm not a fan of RTS or MMORPG games for particular reasons, so I mostly play FPS games, and more specifically realistic FPS games (i.e. not Half-Life, Doom, Quake, etc.), so only playing these types of games, I do not really want to spend too much money on a PC.
ANYWAY, I mostly play Battlefield 2, Call of Duty, some CS: Source, etc. I already am content with the frames per second I get now and settings I have now, but an upgrade is almost always worth something, so I was wondering if it would be best to get some more RAM, get a faster CPU, or get a better video card, which has mostly been answered, and based on how much I would spend, I would get a 7600GT.
Also, I do not plan on building an entirely new system until I go to college, sometime next year, so Conroe, for now, is out.
