either one would suit your needs....the granite bay is a little pricey (not to mention you have to buy two sticks of ram) and the performance difference isnt that signifigant. I just looked up the black pearl from asus and its a sweet little board...just to note that the p4pe BP doesnt come with features such as serial ata or ide raid. So if you wanted to run raid you would need a pci controller card. The Black Pearl comes with a couple goodies such as the usb 32mb flash storage device that you can just carry around with you and the board offers a feature that will allow you to play cds without the computer turned on...Besides that these boards are neck to neck in performance.
