Im just wondering what graphics card i should buy. Im lookin at the geforce 7800GT atm but i cant tell the difference between the expensive versions and cheaper versions (for the most part) any advice on which card i should get or what the differences are? I like to consider myself a gamer too. (only to those who dont judge) *dont worry about sys reqirements, just price. Prolly around $300. Ive been shopping off newegg.com*
