well my philosophy on any project involving performance and buying parts is to just get the best parts im willing to pay for/can afford and let the numbers fall where they may. I never do anything "by the numbers". I for one also do not believe in form following function, if something looks good or is just plain old cool, i want it! I also would like to keep whatever computer i get open to upgradeability, so even if i dont want to buy 2 vid cards right away, i want to get the dual pcie PSU, motherboard, ddr3 capable, and one that can handle the better CPUs even if i dont get one. Thanks for everyone who contributed so far again! And still one question remains....sounds cards, pcie vs pci, any reason for it? It would just make sense to bump up the sound card to one of the lesser pcie slots since the video cards are going to be bumped up.
