I would have thought someone with your tinkering attitude might BUILD your PC?
You will love everything on that PC... I, on the other hand would want a better graphics card for my uber l33t gaming.
Do you want me to be more specific about bottlenecks?
(I will need the mobo model). And also, check out the case and fans - big case with LARGE fans (1 front and 1 back - both 120mm, with dust filters AT LEAST) else it will just heat up, which sucks.
