Thoughts on a new cad system I'm putting together. It has to be budget concious but powerful enough to do basic rendering 2 x Intel 2.8 Xeons, 800mhz fsb, 1mb L2, Hyper Threading, EMT64 2gig DDR2 PC2-3200 ram 2 x Hitachi 160gig SATA Drives in RAID 0 Asus EN6600GT/Top/TD 128mb Overclock limited edition video card. Those are the main components I picked w/cad in mind. Thoughts?
