I know I have the wattage to handle to card.
The machine is just an XPS 630i. Its about a year old. 3.4ghz dual core. 8gb of ram on vista at the moment. I don't really plan on upgrading the CPU cause I don't want to upgrade mother board and CPU together.
Let me know if you need any more information.
Also I have a question. I was looking at 5870, which is a little more than I want to pay. It looks like it is a bit better then the GTX 470 in most games.
My question is, is the 6000 series better that the 5870? Cause the 6000 series of cards seem to be a lot cheaper. Which doesn't make sense.
