not true the +3800 will not bottleneck your 7900gt.
I have a +3700(sandiego) with a x1900xtx and it runs blazing fast.

by the way what kind of RAM do you plan using on your rig??
I'd be surprised if there was a single game that would run faster on a 7600 GT than on a 7900 GT, regardless of the processor.
Which is why I noted that it would be ideal to have the X2 3800+/7900GT combo.
