Rosewill PSU's are a very bad idea. This is what I'd do in your price range:

http://www.newegg.com/Product/Product.aspx?Item=N82E16814102830 $229.99 - $20.00 MIR

Total - $728.30 - $30.00 MIR's

You could save another $30 by going with this GPU instead:

SAPPHIRE Vapor-X Radeon HD 4870 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Retail
http://www.newegg.com/Product/Product.aspx?Item=N82E16814102825 $199.99 - $20.00 MIR

Keep in mind that the new motherboards only have 1 IDE port onboard for a total of 2 devices. You might want to spend a little money and upgrade either the HD or optical drive to SATA if you currently have IDE drives.

If you wanted to save even more money you could get the Phenom II 720 and have enough left over for the new HD and optical drive:

shortstuff_mt is right, Rosewill PSUs aren't that great although there are a few units that are okay.
