It's not the 610 probably will take up next to nothing power wise. They rate the power for CPU's that draw a lot power wise. I would just saying in the future you may want to look towards a new system come the next year or year and a half. Maybe build a machine this time around and get a more overall better system.
Just to clarify, I will be able to use the 610? I was also considering loading Windows 7 on this PC as well.
