Well I can't find any good benchmarks for Xeon X5660's, so I don't know what kind of power usage they take. What I did do was look at users in the DC sub forum who run SR-2 systems with that processor or the one below it. I seen one run a 1250W PSU, but he also powered two 400 series GPUs in SLI. They are power hungry, while another used a single 850W with a very low end GPU. With that being said, I think you'll be fine with an 850W PSU since the FirePRO v4900 isn't all that high end. Though if you want to be a little safer then go with a 900 - 950W PSU.
