Im using the asus p5wdh deluxe motherboard, its good and i have no complaints so far, if you need to change any of the bios options its simple enough. Comes with a nice manual which also includes instalation instructions on everything u will possibly be connecting upto it.

Dunno if u wanna spend that much on one tho mine was £152

Unfortunately ddr2 ram prices seem to have gone up a bit since i ordered ....not sure why that is.

if you want a cheaper one probably best togo for a 965 board for the core 2 duo stuff.

Higgins is right about the graphics cards...but depends if u want to wait.
