trencin :
true I understand that INtel OC's like crazy but my friend does not have C2D he got an AM2 Mobo right now and all he needs is a proc to gowith it when he tried to order the 3600+x2 Brisbane they out of stock on new egg so he is looking at the next lowest thing since he dont got deep pockets. and he really wants the 8800 GTS
Look at the 5600+, 4800+, 4600+, or even the 5000+.
Since your friend already has the AM2 mobo, no need to ditch it for an Intel system. Get the best CPU that will work with his board, for what he is willing to pay.
The 8800GTS 320MB is a good GPU (I have one), and even if the CPU might be the cause of a bottleneck, unless he totally cranks out the eye candy and plays at a ridiculously high resolution, any of the the above CPUs, or even the 3600+ he was looking to get, should be a decent enough gaming system.
