Thanks Linjo! We've played around with K1 grid and Q4000 GPU cards and we're still looking for the sweet spot. We definitely like the performance of the K2 cards the best so far and not all of our shared users would need the performance concurrently, so we were hoping to get the best bang for our buck and still provide high power for individual users when needed. Our quest will continue and in the mean time, I'll hit up our VMware SE as you suggested. Thanks!
