hello werewolf, it seems you are looking for an entry level graphics card. I've had personal experience with a Gigabyte GTS250. This card is an EXTREMELY good entry level gamer card. It could runs games like; all of the call of duties (including the new black ops), mass effect 2, just cause 2, Mafia II, ect ect. I could run all these games on medium-high with 2-4x aa with acceptable frame rates (30-40) at 1920x1080. If I were you i'de buy this entry card NOW to prevent kicking yourself in the pants later when you're getting avg 10 fps.
PS: Best answer me cos im impatient and was some credit on this site !
