Game, yeah just check your power supply. And shame on you for buying a 400 compaq. Have you checked to make sure your motherboard's compatible with the card you want? I'd also like to throw my support towards an nvidia card. I've had nothing but pleasant experiences with them an my last radeon always had performance issues despite it's superiority over my 2002 geforce ti4600. yeah, i could run HL2 with that card at a decent fps. the radeon crapped out after 4 months.
