I have the q6600 and I can't recomend it more.  nstuff anf cipher have theirs OC'd to 3gig each and they ran ultra smooth.I will get around to OCing the thing as soon as i decide to get a thermalright ultra 120 extreme heatsink.  As for the video card i have a 8800gt thats factory oc'd to 700 core 1000mem and the darn thing overheats a lot in games Im sending it back to evga and gttingt he 8800gts 512.  The spped of the gt is awesome and i can't be more happy about it in those terms it's the first version so it's before they fixed the cooler on them. 

decided I'm gonna go with the q6600 and the xfx 8800gts 512 i think...I'd go with the superclock but it's not in stock so I'll just spent the extra 40 bucks or so on the GTS

I have this unspoken rule that 10 bucks a frame is worth the extra green...and the new GTS just so happens to be about 4-5 fps higher than the GT so I guess I'll spend the cash for the performance. I'll be sure to post up score when I get it all in (looking forward to oc'ing my q6600 to 3ghz when I get it...quads really have a significant performance boost when you get them up to the higher 1333 FSB which is what they need to be at to not bottleneck out)

Guess Intel just learned that now as those mad expensive 45nm processors are all 1333...LOL
