Well...not sure if this will help ya...But im piecing together a 1st gen x58 as we speak here are the costs so far
EVGA x58 SLI Board - $60
i7 950 3.06Ghz - $50
CM690 (how funny) - $35
Agility3 120GB SSD - $80
500GB Seagate 3gbps 7200rpm - $25
3x2GB 6GB Corsair 1600Mhz - $20
GTX 285 - $40
= $310? Still loooking for a working used PSU of good quality and the build wll be done!
Im guessing total build cost for gas money aswell to be around $400.
However I am expecting to sell this unit for $700 swapping out the video card for a 660ti 2GB I bought for $200. Bringing total cost around $610. Aso gonna put 12GB ram in it just waiting to RMA it.
