That pre-built machine that Jakg posted looks a good enough deal unless you want to go to the bother of spending hours, in my case days emm make that weeks

trolling through websites, reviews etc figuring out all the components that you want.
I recently built my very first ever pc from scratch and it is not that scary really. I ended up buying stuff from all over including second hand GFX card (8800GTS) and CPU (E6750) from ebay. At the end of the day I am proud of myself that I've done it although my shiny 'special edition' Antec P182 case is just bloody awful to look at, no idea what I was thinking there a head up my own bottom kinda moment.
Probably saved myself a couple of hundred quid doing the home build and actually learned lots in the process.
Unless your stinkin rich I really don't see the point of the new ultra high end components, my average system runs GTRevo, iRacing etc on full graphics no probs.
I'm not sure about other mobos but the Abit IP35pro XE board that I got is quality manufactured, easy to install and set up and also easy to overclock from windows using Abits software.
Anyway good luck on whatever you decide to do
