Judging on the latest achievements and actions of AMD/ATI, we can expect good price/performance products in the futur. Expect from the SB600, I love my 790FX board. It did not cost a lot of money and it is way better thant my old nforce570 wiche was good. The same goes for my 3850, it was a good buy. But the arrival of the 4xxx series is astounding! So if the same goes with these chipsets.... They should be of great value/performance.
I will not comment on the CPU's as they are not the main subject here.
