OK, believe it not, this is the only board Newegg has that i can be sure supports X6 AND will run 1066 memory on an AM3 chip.
MSI 790XT-G45 AM3/AM2+/AM2 AMD 790X ATX AMD Mother...
Most of the boards will only run it on AM2+. The ones that clearly say they can do 1066, don't support X6.
There are a couple of Jetway boards where you can't really tell and none of those seem to have any support material on the web site.
So, that's it. I'm done. I've got one 'for sure' choice and that's what I'm going with - for better or worse - we shall see.
Thanks to everyone for their input and critiques. It's appreciated.
Robin.
