I must be on the wrong bus then because I can't see the point in buying a 6 core CPU when 2 of those cores are going to go to waste for the things jstocky14 listed.
The £60 pounds saved from going for a 1100T to a 955 BE could be better spent on upgrading a 560TI to a 570 which is more important when it comes to games anyway. The reason I'm suggesting the 955 BE is that I heard that they can be pushed to match the speeds of the other 4 cores that AMD have on offer. As AMDFTW said, a 555 BE would run SC2 just fine and I know this for a fact as I've played the demo many times over on the better half's PC which has a 555 BE and 6850 but from what I've read then SC2 does benefit from a four core CPU

As for an AMD motherboard, I wouldn't say you need to get a 990X chipset board (although they are the best atm on the AMD side) but I would suggest a board with a AM3+ socket because then when it comes to upgrading you could get a bulldozer CPU before upgrading the mobo if you wanted, although you would need to upgrade the mobo at some point to get the best out of that CPU. These are the AM3+ socket boards that Aria have just to give you something to go on:

Like everyone says though, the best gaming CPU is the 2500K is the and Aria do a great bundle package

I'd personally price up the case, PSU, storage, memory and graphics card you want and then decide with the money you have left if you want to go for the 955 or the 2500K. 2500K is the best but the 955 BE will kill SC2 anyways. Just make sure you get a good graphics card so you can play it maxed out
