I am hoping that someone can help me. I have a dell dimension E510 which currently has a Radeon X300/X550/X1050 Series video card. according to the starcraft 2 site I need 128 MB PCIe NVIDIA® GeForce® 6600 GT or ATI Radeon® 9800 PRO video card or better. is there a video card that fits the requirement that I can use with the dimension E510? I read somewhere that the powersupply is not enough to suport the more beefier cards. can someone help?
