For about $280 or less...I haven't checked it with my discount... I could get you a GeForce GTX 260 (One step below the Top-Of-The-Line that is out today video card), But if you do go with that one be sure you can fit it in your case, It's a very large card.
O-yeah by the way.... what type of "BUS" do you have? PCI? AGP? PCI-Express X16?
Also what's the wattage on your PSU you have, 400w 500w 600w?
Then again you would most likely get a better price on
www.newegg.comAnyways, let me know if I could be of any assistance.
I could get some pretty crazy prices on games, cables etc. (JUST LET ME KNOW)
Just a heads up for a new game (If it like just came out today) 49.99 I can get is for 42.99 so plus tax.....about 46.85 (that's using 0.09 for Tax) let me know if your interested.
It's not much, but hey it's a few bucks....
Well take it easy,
Joe
