Reschke,
I would get a E6600 or even a E6400 processor. They will still overclock beyond E6800 speeds. The only advantage to the 6800 is the unlocked multiplier. I dont think its worth it paying such a premium for that.
The other parts are great, you will love the Geforce 8800GTS.
I'm running an E6400 on a EVGA 680i motherboard, running at 400 x 8 = 3.2Ghz. Very, VERY fast. Also my PNY 8800GTS is overclocked to 600/1000. I can run Oblivion maxed out at 70FPS average, and LOMAC with everything maxed out and 8xFSAA above 50fps all the time.
If you plan to overclock, get a good cooler. I use a Tuniq Tower 120 and love it, but its hard to find a place with it in stock.
SkyChimp,
I would suggest you lurk before you post in topics were other people know what they are talking about. Also, brand loyalty is idiotic.
