you can get that down a bit with combos and rebates.
I'd suggest using the new 1075T, which is a 3.0 GHz processor instead of 2.8, and seems to be a cleaner process build over the 1055 and 1090, and several articles are reporting overclock in excess of 4.0 GHz. Overclockers.net got one that ran at 4.0Ghz with a cpu temp of only 46C. Benchmark.net tested one at a 24-hour stabe in prime95 overclock at 4.15 GHz. Another article was able to at least run a 3DMark benchmark at 4.5 GHz, though that wasn't tested for long term stability.
If you aren't planning such extreme overclocks (though 4.0 should be easy to do if you want) you can go with an 880GM or 870 motherboard which will handle single card graphics just fine.
