Hey all, here's the picture of my setup that I've been meaning to post for a while. What you're seeing is the following

AMD 3800+ Main machine (CRT in middle) with 7800GTX
Core 2 Duo 2.33ghz Secondary machine with 7800GTX running (2) 22" LCD's mounted vertically on Neo-Flex stands
Logitech G15 and X-Keys Pro (love it)

I'm playing 1 Prot Pally (46) and 4 Elem Shammy's (45)

So far instances are cake. Have done Deadmines, Stockades, SFK, SM (all), Uldaman, and ZF all the way through within the correct level range. It's a blast!

Enjoy!
