That would be a good setup, but I am unsure of what IC that memory is based on. The place I used to find out what IC's were used on what seems to be gone now.
It would be nice to have Micron D9 GMH so you could pull some OC's off without having to worry about your RAM konking on you. The nice thing is the price of 8500C5 sticks these days.
The P5K with some easy Vmods is a killer low cost board. I almost bought one untill I found the pencil Vdroop mod for my 680i
I think I will wait for X38 Intel based boards
