opinions on this system

i could spend up to 4500 plus tax but i figured that the extra 1000 wasn't worth the slight performance gains of RAID 0 with 2 150g raptors and dual 7800gtx, and fx-57,
what do you think

yep me too buddy waiting for the ddr2 amd claims by the end of the year they will have ddr2 ready to go
