I'd stick with Intel. quad 2.4 for $179 is crazy good. I just put a GTX 260 in, and it's awesome. I had an 8800GTS G92 in there before, and te 260 blows it away. Having more available memory on the video card is the main reason I went that way over say a 9800GX2, or a 9800GT. I might even use the EVGA 'step up' program and get a gtx 280 in a few months. Either that, or ill go SLI whenever they release the drivers that allow multiple monitors under SLI. Maybe that will solve the issue of extreme FPS drop when a wow window is put onto the monitor attached to the secondary video card.

I have the same case you are looking at. It's a nice case. It does tend to draw in dust, I constantly wipe down the front for dust, as its constantly covered. It does keep my case very cool. My motherboard temperature is always just a few degrees above room temperature, and my CPU is at a constant 52 degrees C at full tilt, and it's OC'd to 3.3ghz.
