I'd rather have the CPU be the bottleneck than the GPU. After all, you won't be able to really tell a difference between an E6700 and an X6800 (I have the former). Trust me - an extra $500 into your CPU won't net you extra FPS in Oblivion or... well, Oblivion is
still (though not for long) the most graphically demanding game. If you are going to spend $1k on a CPU, get the QX6700. If not, just get the E6700. Also, my 680i worked perfectly out of the box (though I did run into a problem when I ran a BIOS hotfix, which I didn't even need because my SATA drivers were fine, where it lowered my Ram voltages to default while keeping the timings lowered which resulted in the system shutting off every 30 seconds until I figured out that I needed to reset the timings) and has been stable since.
If I were you, I'd get a 680i motherboard, 8800GTX, 2GB DDR2 800, X-Fi Platinum, 2x 320GB Seagate HDDs, 2x DVD-Burners, a decent power supply and case, and Windows MCE 2005 (with free upgrade to Vista Home Premium
😀 ). The Platinum's Front Panel is really nice, and I'm actually enjoying watching movies from my bed with remote in hand. The bundled Media Player (actually, it's more of a Media Center thing like Microsoft's) is really growing on me. Here's a pic of my PC:
3dMark06 - 11,630
92.3 avg FPS in CoH @ 1680x1050, 62.7 avg FPS in F.E.A.R. at 1132x1040 (or something like that, it's a funky fullscreen resolution because my monitor is 1680x1050 and F.E.A.R. only does fullscreen - need to see if I can fix that), no lag in Oblivion at 1680x1050 with 4x AA (8x AA lags slightly from time to time), HDR, 16x AS, Full Shaders, and Full Viewing Sliders, Dark Messiah of Might and Magic (comes with 8800GTX
😀 ) at max settings, and Call of Duty 2 at max settings with no lag either.
It does everything I want it to and more. I don't have the hard drives in Raid-0 because I keep downloaded stuff on the secondary hard drive so I can just reformat Windows without losing everything. It's pretty damn sweet.
