Getting back to the original post.
the setup you have and suggest will only require a 750w PSU at most.
this will even allow for expansion such as SLI cards, a spare HDD etc.

for gaming purposes I cannot express the importance of Memory in both fashions.
you are getting Win7 64b I recommend a MINIMUM 4GB
Its cheap right now, so its not that much.

Swap, very touchy subject for some.
You didnt list your HDD so I am going to guess that its a Run of the mill typical 7200rpm 500 GB.
with the price free-fall on HDDs right now... you might consider a stripe

If you play MMOs with PvP or high resolution games as I think you do, you may want faster read/writes. This can be achieved by either SSD, SCSI or RAID.

It will definitely support a small array with no difficulty and will actually make better use of those kick-ass channels. all you would need to do is order 2 500GB HDDs. Just something to consider
Thing is, with Win7 its SUPER cake to set up. Seriously, you just switch CDs or use a thumbdrive or a second CD drive for the drivers.
It's so easy, a caveman can do it.
