According to xbitlabs, the Phenom II X4 965 is on the 13th, Athlon II X4 630 is the 23rd, and the 600e/605e after that. So more waiting on the 45w quad core. No news on the 45w X3.
I know I can use an AM3 cpu on an AM2+ motherboard. I'm a little concerned that the motherboard BIOS won't support the AM3 cpu initially, which means I will have to flash an updated BIOS. But I can't flash without a working CPU, or can I? If not, a catch 22.
In addition, the AMD ITX market is pretty slim on choices right now. I haven't seen anything new since the Zotac 8200 ITX back in December. I really really want to see more AMD ITX boards come out for these 45w X3/X4s.
