X38 is based phased out. Buy x48 instead. Look at the Asus P5E Deluxe.
Ok you put in caps that is a GAMING system. RAID is USELESS. Get rid of it. Don't double your chances of data loss for zero gain.
What the hell is Hi-Power? If you ask yourself that question with a PSU don't buy it. See if you can the PC Power and Cooling Quad 750. Great PSU.
At 1680x1050 you don't need two 4870 video cards. The second card will offer little extra benefit in all but a VERY few (count them on 1 hand) games. You would be better off looking at the 4870x2 which comes out in August.
Gaming system- dual core FTW. Quad will not benefit you enough. 8400 can be easily be o/ced between 3.6 and 4.0.
thaks for reply!
anyway, what Windows (Vista) ? 32 or 64 ? with for 4Gbs of ram... but what if games don't support 64, I havent made any reserach about that yet...
If your going to get 4gb of ram, you may aswell go for the 64... its future proofing in theory.... also, now that vista has been out for a while, future games are surely going to support 64bit (surely?)
