I just can't believe my luck: I scored an AMD A8-3820! And for a decent price as well....
It seems that the FM1 stocks are being cleared, as I also managed to obtain the king of ASUS FM1 mobo's, the F1A75-V EVO, for a price below 90 Euros!
If I can't install Ubuntu on this combination, I will throw the windows open and go back to the camp of Gates and Balmer.

If Ubuntu settles well and I win the lottery this month I will also buy the Gigabyte and Asrock top FM1 mobo's and stick them with A8-3820s.
If the price is big enough I will repeat it with the FM2 mobos of the same companies together with a trio of A10-5700s.
Then I will make ASUS happy by buying a pile of HD 6670s and start experimenting with Triple and Quad CrossfireX.

But first things first: installing Ubuntu (or any other flavor of 64-bit Linux) on the F1A75-V EVO/A8-3820 combo...
