I'm the opposite. Overclocked quad-core i7 and 24GB of overclocked DDR3 RAM is more than enough, but though I can make minimum requirements, I can't reach the recommended specs because I don't have a graphics card to match. I'll put this next bit in bold so that someone who migh know will be able to see it at a glance:
Is it possible to overclock a graphics card, and is it worth doing?
It's possible (generally the difference between graphics cards in a model line is just clock speeds and memory, for the most part) but of course it's associated with more cooling issues and some graphics cards are already running pretty close to the fastest they can.
My single core Pentium 4 sadly fails that test I guess that's why I can only get 30-40fps in Racer.
