Think I got the build... want someone more experienced to look over

what about 64-bit.... i thought 32 was the way to go. can someone explain the difference?

32bit can only address up to 4GB system memory (that's including graphics memory)
64bit can make use of way more. It doesn't really have any kind of compatability issues any more so I'd recommend going with 64.

if you haven't ordered yet, you might want this PSU instead, 100 more watts (600) and four 12v rails instead of two (18a each), it's not modular though, but it's only $40 after MIR...
