If i go with the hd4850 would I have to go with a motherboard which supports Xfire and if so which motherboard would be a respectable choice? Since my total so far has reached 680.43 not including the GPU i have about 100 - 150 to spend on a motherboard.

Also which one is smaller the 8800gt or the hd4850?

I started looking at a couple cases and Im sort of interested in these 2:

When looking at reviews the coolmaster seems like a more solid case but it is a tight fit. For a motherboard I would consider SLI over crossfire if I need to choose over the two. Also is the Ati 4850 much better then the 8800gt? When looking at the prices on newegg, the 8800gt seems to be cheaper and has alot of good reviews.

Thank you for the suggestion on the PSU I think i will go with the 550VX.

I want to build a PC for gaming and school, but my budget this summer isnt that great so I basicly want to get everything but the graphics card and the sound card for now. My budget without those things are $800 - 900.

I know a couple parts I want to go with:

CPU: Intel Core 2 Quad Q6600 - $199.99 from tigerdirect

Cooling: Artic cooling freezer 7 - $31.99 from newegg

RAM: http://www.newegg.com/Product/Product.aspx?Item=N82E16820145184 - $86.50

HD: http://www.newegg.com/Product/Product.aspx?Item=N82E16822136074 - 64.99

Burner: http://www.newegg.com/Product/Product.aspx?Item=N82E16827151154&Tpk=Samsung%2bSH-S203N - 26.99

Windows Vista Home Premium SP1 64-bit - 99.99

The problem is I really dont know what a good motherboard, power supply, and case would be. For a graphics card though I would probally get the 8800GT. Any help would be appreciated, I should be able to build it late August.

Thanks everyone for the help.
