nope, the mobo should have two or 3 video card slots. unless the mobo is the new socket 1366 for i7core. most likely puwede SLI (nvidia), puwede din Crossfire (radeon) at the same time.
you can get a sli supported mobo * 1.8k though. but that's the oldest sli chipset. that's what I'm using right now Asus P5N-sli. however, I realize SLI is for future proof. buying a 2 less powerful card in SLI is still not as good as the highest end Card. I'm swapping my SLI mobo to another so I can proritize overclocking cpu instead that my current cannot reach.
btw, I hear Xeon chip is good for servers... looks good on everest 5 too.
