Unfortunally you never know if a certain combination of components will work OK until you have actually tried. I had to RMA my mainboard on my new custom built PC because they couldn't fix a problem for more than three months.
I would definitely go for Gigabyte at the moment, I would opt for an Intel based board though. Current ASUS boards / NVIDIA based boards are way too buggy. As far as CPU goes, I bought an Intel dual core. Was the better solution half a year ago, might have changed since then.
Cool, thank you for the info!!!
