Aces High doesn't utilize more than one core in an AMD multi-core processor. So I would recommend Intel if Aces High is what you're building your computer around.

You'll also need DDR3 memory, so keep that in mind.
I don't know if I would spend the coin on going from a ~800 to a ~900 watt power supply just because of some Newegg calculation though. Your 800 watt is probably good enough
So decide on your CPU first. As mentioned Tom's Hardware has lists, and you can use
this one as a rough guide. Different benchmarking software can give different results and you certainly need to balance that out. But this guide can get you close.
The 1090T is not anywhere near as capable as the Sandy Bridge i5-2500K. For the exact same price it is a no brainer if you re-consider the warnings about AMD CPU's and Aces High. For the i5 Sandy Bridges, for only a little more money you can get the 2500K over the lowest priced 2300 that
BoilerDown first mentioned, overclocking or otherwise, and I personally wouldn't even look at the 2300, 2400, 2500 and move right to the 2500K for the sake or around 40 Bucks. But that's me.
I too have always been a fan of ASUS boards, but close study of the P67 boards they have released for Sandy Bridge have a lot of complaints on both NewEgg and the ASUS support forums. I expect it's mostly BIOS (or noob) related and this will likely get fleshed out; just be aware of a rocky road for quite a few people with these boards. Dual boots, long POST times, picky with RAM even RAM listed on the QVL to name a few.
Good reviews and excellent features on the
ASRock Extreme4 with a good price. The P67 Gigabyte boards all seem to have lesser features but no shortage of price.
- CPU of either 2500K or 1090T = same price and no contest in performance. Advantage 2500K
- DDR3 RAM which you would need with either Sandy Bridge board or one you listed for the 1090T = same price
- The mobo you listed for the 1090T does
NOT support SLI and only has a x4 second PCIe slot
- Sandy Bridge boards with SLI will
begin around the price of the Extreme4 I provided = 160 bucks
There are a bunch of boards available, do your research for the features you need, put a 2500K in it with some good 1600 DDR3 RAM, keep your PSU and those rocking 2 x 470's and you'll be kickin'!
