upgrading video card dimension 4600

[flyguyspy]

what up guys
i gots this dell dimension 4600, its got a fx 5200 in it, which pisses the hell out fo me. i need a new card, but this dude told me once that becaus the cassing is super compact, they take only certain cards. is he smoking crack or what?
im not too sure about any of this shizzer yet but its progressing
any special recomendations for cards? nothing like 600 dollars.
more like the 250 price range.

well any card should fit but small cases can only take cards that are a certain size or smaller like a small form factor pc, your comp looks like a mid tower so ya any card should fit, and i recommend a 6600gt for about $200. remember to get the agp version of it
