I am quite surprised there is not a sub forum for hardware. So what are your hardware specs. What is the most cpu intensive software you run. What would a typical professional 3d artist or game programmer use at the high end?
I can imagine a system at the very high end, dual xeons, dual quadros, 64 gigs ram, raid 5 ssds, dual 30'' monitors. Is that not a bit overkill though considering the amount it would cost when you could still manage it on much less.
Also what are some good monitors, I assume most people want touchscreen?
