I highly suggest you do not be closed minded to AMD as Intel finally has made a good chip again. The Core 2 Duo's are better than the AMD's out right now and theres no question about that. I mean the X2 6000 is still a good CPU but you just said a video card that won't be outdated in a year while the mobo for Core 2 Duo's will be used for new chips coming soon while the AM2 board's are older and you will not be able to upgrade very easily....I'm just saying it's nice to be a fan but there is no question that Core 2 Duo's in that price range are the top chips out there.
Also as someone stated at that resolution the 8800GTS 320 will not be able to handle things too well in a little while. Go with the 640 version since you have chosen a large monitor.
There are better CPU coolers out there for the money btw..
I like the PSU but I prefer this PSU over that one any day
