This is more of an FYI than an actual question, although I would like to hear your thoughts on it. Those with old AM2 boards, take note! You may be in for some good news.
I have an Asus M2NPV-VM mobo, a mid range AM2 board that I got three years ago. It's pretty out of date by now and I've been keeping an eye out for a replacement, but things are a bit tight on the budget front as far as toys are concerned.
Anyhow, my old mobo may just have received a new lease on life. Until very recently the highest CPU it could support was the Athlon 64 X2 6400+. The list didn't even include Phenom I's. Then quite by accident, I stumbled across a BIOS update on the Asus website (still in Beta though) that enables support for all the new Athlon II / Phenom II chips all the way to the 95W X4 945! See link with the updated support list.
This is obviously very exiting, as it means I can drop in a brand new chip that will be a massive upgrade from my old X2 5600+. Or would it? How much would my old mobo+ DDR2 RAM hold back the potential of an Athlon II / Phenom II chip?
I'm also a bit concerned about that Beta tag next to the BIOS update. If it doesn't work I'd be wasting money on a new CPU.
