I just got one but my Marvell controller doesn't let me hit the max speed of what this ssd is capable of and was wondering if anyone knows a cheap sata 3 card i can pick up from either newegg or amazon thanks.
Most "cheap sata 3 cards" will have a controller not any better than a Marvell controller. That said, based on my limited experience benchmarking with Sata II cards, if I had to try a cheaper sata III card right now, I'd go with a Highpoint over Syba or Rosewill.
You're probably better off just using the Intel SATA 3Gb ports instead - it'll limit the max sequential speed but the real benefit from SSDs is the random performance, and the SATA 3Gb ports won't limit that at all (and will be better than the Marvell ones).
