Well I found a solution and set it up today. I went back and forth between buy a mac pro to drive all the monitors or building a PC to drive them all. After reading about some complaints about the mac pro multi monitor support, and after looking at benchmarks I decided on the following setup. This is giving me the best of both worlds, with the power when I need it.
Monitor stand from here, not bad for $168.95

I combine both machines using Synergy. This allows me to use one keyboard and mouse for both, and use them like one continuous display. I have to say I am very satisfied with the final results. Its been a while since I ever touched a PC, but the combination has left me pretty happy. Considering I can now play games at around 6x the frame rate of the mac pro, I have faster benchmarks in general, but I still can easily run my mac apps, it was a good compromise.
On a side note, the picture on these monoprice monitors are almost identical to the thunderbolt displays. Less then half the cost..
