I personally can't stand starting a PC game without setting all the sliders to maximum quality. I get major angst if I can't do that!
So im sitting most of the PC gaming out until my next big upgrade mid/late next year.
Core I7 quad
8gb RAM
Windows Vista 64
2x Top of the line Direct X 11 hardware
Antec P182 Case
Currently* PC power and Cooling Silencer 750W
So for now the Xbox 360 is sitting under the 53" TV, but next year things may change.
Tease.
