if you need anymore info about my machine please ask, and if this video card isn't compatible can you please point me to a different one that would be compatible, thank you|||well, what is your PSU specs (power supply), it has to be high egnouph 2 support the card. besides that i think it is compatible. (you may want 2 buy another gig of RAM probably like $20 now) i would think a 500 would be able to (depending on other things), but a 750 would be better|||it should be more than fine if your psu is at least 375 watts|||all you really need to know is if you have a free pci express slot on your computer that is open, if so..its compatible|||yes that will be compatible with your computer, as you have pci express 16, although i would upgrade ram if you want to run games ram is normally most effective when running games, for reducing lag.
