Ubuntu Asus & GigaByte H67 M/B support

HI,
I'm considering of buying either one of these M/Bs that have everything on-board (VGA, Lan & Audio), 4GB Ram & an Intel Core i3-2100 (3M Cache, 3.10 GHz) and install Linux Ubuntu Desktop 12.04 LTS 64bit to utilize the 4GB Ram.

Intel Core i3-2100 (3M Cache, 3.10 GHz)

I noticed that neither manufacturers have Linux Drivers for their M/B, so will all the M/B components (H67 chip-set, Lan, Audio, VGA) will be recognized by the Ubuntu installation. I'm concerned whether the on-board graphics processor of the chip-set & CPU will work in Ubuntu?
Or whether I should get a separate PCI Express 16x VGA card (NVIDIA / ATI) that both support Linux.

Otherwise , which other equivalent M/B would be 100% compatible with Linux Ubuntu...

Thanks in advance
