Hello,I know very little about upgrading my computer. I was given this computer as a gift. It is an HP pavilion elite e9120y with a Pegatron M2N78-LA motherboard. My father has a spare 500 watt corsair power supply I can have if I find a card worth purchasing. My budget is around $200. Im very afraid to buy anything without help because I am aware that my space is limited.Im sorry in advance for anything I may have left out of the description. Thanks
I should have mentioned that I currently have a Galaxy GT240 512mb ddr5. It is a pretty short card but will not play The Witcher 2 which I just got. This game is the reason I want to upgrade now. The GTX 550 may be the best that I can fit in there.
