Thanks for the advice Chem. It looks like I'll be waiting a bit before building my next PC.
The really sad thing is my MacBook Pro (when the damn thing ships) will be my current gaming rig. With a 2.0GHz Intel Core Duo processor and a 256 MB ATI Mobility Radeon X1600 will most likely kick my current 2.4 GHz P4 with a 128 MB 9800 PRO's collective ***.
So, I'll have what? Doom 3 and Tetris to play until I upgrade my PC
Chem will this be a good gaming rig? What are the bottlenecks? . The hard drive is what stands out to me.
