looking for gaming computer advice

[klu]

i will be building a computer myself

i have a budget cap of 1500$ including shipping and tax

i live in central arizona

this computer will be used primarily for gaming, primarily for ps2

i will be building this computer from scratch

my monitor is 21.6in 1680 x 1050

buying an os is included in the budget, i was planning on win7 pro, but open to suggestions

i need to have a card reader included in this budget with a board that supports usb3.0, open to suggestions for sli or a sli board for future upgrade

no plans to overclock but it is a possibility

i would prefer to start ordering parts immediately

any advice from vets that know of hardware that gets solid performance in ps2 would be appreciated, thanks
