if your going to buy a mobo from newegg becareful. not all the ones they say are compadable with the x2 chips. make sure you double check with the manf. website. I just bought the A8N-SLI and it said on newegg was compadable with the 64, fx, and x2 but its only compadable with fx and 64.
and on the gfx card personally i like nvideo. they have a longer life span for me anyways. I have gone through 3 ati cards in under a year, when the norm nvideo lasts a year or more. Plus also if u can look into it try to get a card with lifetime warrenty, and an upgrade plan. I know the one i just got for 90 days i can upgrade it for the difference in price.
