If it's for gaming, the Phenom II 955 is just as good and cheaper. Also the good AM3 mobos are cheaper than the 1156 mobos and you'll be able to upgrade to 6 core cpus. Check the Homebuilt Systems forum, there are lots of ideas. IMO you should go Phenom II 955 + HD5770, for gaming the most important is the video card, not the CPU. For instance, the cheap Athlon II X3 440 + HD5770 is better than the i5 + HD5750.
