Both of those board are using nVidia GPUs, and nVidia has, as far as I know, not yet released a FOSS driver that supports a 64 bit OS with full functionality. Intel, on the other hand, has, I believe, released a FOSS driver for their GPU.
You may want to consider this issue before investing.
(Perhaps I'm biased since I primarily use Fedora, and have to rebuild my nVidia driver every time the kernel changes since my laptop has a nVidia GPU on it's m/b. Oh, I also have to do that when the kernel changes on my Kubuntu 8.10 but the Jaunty repository's dkpg for nVidia seems to be working. Note: My laptop uses 64-bit OS versions for all my distributions.)
