As the title suggests, I'm looking for an AMD mobo, I was going to go with the i5 2500K etc but to get everything to compliment each other works out more money then an AMD build. Currently using a 550BE which can be unlocked, but my mobo doesnt support 125w. The new mobo would need to support BD as I will either get that or 1100T (depends on price) and SLI 2X16.
I could push £240 with a cpu cooler aswell.

You could opt for an AM3+ mobo and GAMBLE on it unlocking to a quadcore (this will need an aftermarket heatsink!). You are also gambling that bulldozer is atleast on par with sandybridge for the price you'll end up paying.
