You will never overclock your CPU with a B75 motherboard. You need P67, Z68, Z75 or Z77 for that.

Samsung, Crucial and Intel have the best reputations for reliability.
There have been some amazing SSD sales lately. If you are willing to wait a bit and check deal sites like slickdeals.net every day you can get a 256GB Samsung 830 for ~$200. The Crucial M4 is also still a great drive and usually quite a bit cheaper than the Samsung. I have also read Intel is dropping their prices soon but I'm not sure on what models.
