Trying to see how expensive I can make a desktop. Record so far is $26587.74 for the Falcon Northwest Mach V. If you're paying THAT MUCH for a desktop, you'd better expect it to run Crysis like it's nothing.
Have you ever seen the "dream machine" Maximum PC builds every year? They pretty much get the most powerful stuff currently available and throw it all together. They always end up spending an obscene amount of money.
