Have a look at the Asus P6X58D-E or Gigabyte GA-X58A-UD3R as these offer decent savings and unlikely to cut out any features that you would need/use.
The drive listed is a slow 'green', which doesn't offer significant power savings over a much faster performance drive. So I'd suggest changing that to a Samsung Spinpoint F3 or Seagate Barracuda 7200.12.
If you're interested in CPU upgrades then maybe AMD would be the better option as they seem to be planning to keep the AM3 for longer than Intel is planning to keep the 1366/1156 sockets. However if you want to keep the CPU for basically the whole life of the build (and only upgrade GPU) then it's the better choice IMO due to the massive amount of PCI-E lanes.
a lot of what you just said went thoroughly over my head o_O can i get it a little dumb'd down?
"No no for the 5.4k F2 : hit the 7.2k F3" translates to: Buy the faster Samsung Spinpoint F3 for $75 instead of the F2 EcoGreen.
"Crazy CF options on AM3? Have a look at the 890FX chipset": If you want to do tri/quad-GPU CrossFire on a cheaper AMD setup (spending less on processor/mobo/RAM allows you to spend more on graphics), look at the 890FX chipset.
