[Scalping Chief]

Well, I just bought a new Graphics card,
Asus® N6600GT/TD - GeForce™ 6600GT GPU w/128Mb DDR3 & 8X AGP
250 Bones. Did I get ripped or anything? I have a 30 day money back guarentee thing, So I can get my money if i change my mind, And how do I find out if this will even work with my computer? I bought it cause I wanna play BF2 and I had some money to blow. Some of you computer dudes help me out.

EDIT: Or is there a better one I could get for cheaper off some Internet site. Canadian stylie?
