Motherboard in combo w these components...

Hi,
I am new to these forums, but I am hoping to gain some advice on a decent motherboard.

The computer I am building has these components:

-i7 940 (2.93ghz) CPU
-Radeon HD4890 Video Card
-2x 1TB HD's (RAID 1)
-8 GB RAM

What motherboard would work well with these components? I have a good sized budget, so I am willing to shell out a bit more if it allows me to make upgrades over time, install more RAM in a few years, etc.

If you want to know, this computer will be MAINLY for HD computer animation/editing, with some gaming on the side.

Thanks!

I'm not sure about overclocking this. I won't be gaming much, and I want it to be very stable for rendering. Are you sure about the 920? I do have some cash to burn on this build and I don't mind shelling out a bit extra.
