dude sorry some things wrong there but yes great in theory
1. ssci drives go at 15k fastest sata is 10k
2.windows gets b*tchy when you go at or over 2gb of ram
3.Ati uses crossfire not Sli simmilar though
4.those 512 ati cards are just flash the more expensive 256meg with a better gpu is the best ati card at this time I think.The 512s are just to lure people thinking memory is the only thing that matters remember pipelines and the gpu are just as important.
I am not raggin on u so do not take this the wrong way.
And if this I a fantasy comp post I did not know.
