Just for your information: Most SSDs use exactly the same Flash Memory and exactly the same Sandforce Controller. The problems that occur are usually the mainboards fault(if the SSD is not broken in which case you should get it replaced right away).
And a good SSD really can remove the stuttering in town and other loading lags by 99% (it's not just the transfer speed but also the seek time which is only like 1/1000 of a normal HDD).
