My suggestion is to save up a bit more cash and build a better system. I feel the need for a shamless plug, so I'll water cool your computer if you want.And the reason I suggest you wait is because you're not going to be able to upgrade much for 赨. Once you get the processor and motherboard, you don't have anything left over for a video card. Wait till you have about 踰, then you can get a pretty good system.
My system
Thunderbird 1.0Gig @ 750 (stupid motherboard)
EPoX 8KTA2
256 MB Crucial CAS2 PC133
20 GB Western Digital 7200 RPM
Creative (eww) GeForce2 MX
Oh yes, and it's watercooled, so as soon as I get a new motherboard, I'm overclocking this bad ass.
