Before you buy I would suggest reading Tom's August SSD review article.
This paragraph is of extreme importance IMO:
"There's no debating whether SSDs offer blistering performance. That that doesn't really matter if you can't trust the device holding that important information. When you read about Corsair's Force 3 recall, OCZ's firmware updates to prevent BSODs, Crucial's link power management issues, and Intel's SSD 320 that loses capacity after a power failure, all within a two-month period, you have to acknowledge that we're dealing with a technology that's simply a lot newer (and consequently less mature) than mechanical storage. "
OK! Your motherboard supports SATA 3 6Gb/s ssd's. That eliminates the Intel 320. The Intel 510 is not really suited for gaming. The OCZ Vertex 3 is a "Plug-n-Pray" ssd equipped with a "SadForce" controller. Nothing left.
The Crucial M4 is a popular ssd and it is relatively trouble free. There was an issue but Crucial issued a firmware update that not only fixed the the problem but also increased performance.
