Right, i built a system with a q6600 quad core, 8 gigs of dd2, and a pretty standard($120) 8800. This is a mad fast system, and it can easily handle 32 million polys in mudbox2. Total cost of the system was around $1100. 2 280's is just..... crazy overkill, a decent 8800/9800 will give you all the performance you actually…
