I have a 150 dollar mobo that has lasted 5 years.
A 2600k is faster than a i7 960 and has an unlocked multiplier to make overclocking very easy. http://www.anandtech.com/bench/Product/45?vs=287
Personally I would buy a good 200 board and put the extra money into a nice 128gb SSD for a boot/gaming drive. You'll see and feel much more of a performance boost that way.
