fastest proccers are the i7's but those are over 300 bucks for the cheapest ones
the best overclocker is the new amd 940 its only 240 dollers, but it takes 40 off if you buy a motherbored with it
and the best graphics card is the new 295, but i heard it was a power hogg, like takes 600 wats just to power one,
the second best is still the 4870 by ati, lol it takes 600 wats to power to, so i would go with a amd 940 and a 4870, there both cheaper, theres not enough proformance differnce to pay the extra 300 bucks
