Hay guys, mobo advice?

I'm getting a new rig soon, as mine is pretty outdated.
So far it consists of:
Intel Core 2 Duo 2.66ghz
Whatever 500gb HD
Radeon x1950XTX
DDR2 RAM (2gb) 800mhz
But as you can see, it lacks a mobo.
It needs to be a slot 775, and I know fuck all about these things.
SO any of you got an idea?

I heard somewhere the 1950XTX will be DX10 compatible..
Also I've decided on a mobo, GigaByte 965P-DQ6 will probably be the one.
Oh and thanks on the perpendicular recording tip, the wiki article was a good read.
