Thanks for all your valuable assistance with this decision.
While it is true that at this time I only need about 850 Watts I also find that the limited number of connections on these PSU's will limit future upgrades. I also appreciated the input about the size of the units as that completely slipped my mind when I was researching PSU's. It's always the little things that bite you when you overlook them. Lucky for me I have a full size case with lots of room.
@ Pizzaman: As to the lifetime warrenty on the Ultra, You must have got it at the right time because it only has a 3 year limited warrenty now. I have had a number of Ultra's that have worked flawlessly over the years and for that reason almost ordered the X3 on sale for $199 but it went up to $249 yesterday.
After taking all advice into account I have decided to order the Cooler Master Real Pro 1250 (It has room to grow, a wealth of connectors, and it's SLI certifed by Nvidia for my hardware).
Now All I have to do is wait for the delivery.
