I've been wanting an SSD ever since they came out, and with the massive load times on Civ 5, and just wanting to have a super fast storage device I've decided to get one. I was looking at getting either a Mushkin or an OCZ that was at least 60GB(but more if its within my budget) and to be no more than $200.
If you want the fastest I think the C300 is the fastest of the bunch. SATA2 backwards compatible and its the only SATA3 SSD atm. It is also faster at loading by 3-4 seconds in games based off reviews I have seen.
