Definitly go with 2 Intel X25-M G2.
I've read more than my share of reviews and digged a lot of forums and they are the absolute kings of SSDs. Their only drawback is a CONSTANT 95 MB/sec sequential write. I know the specs are 70 MB/sec, but the G2 is faster than the G1 (first version), they just didn't update their specs. As I said, their only drawback is a slower sequential write speed, but pair 2 of those in RAID-0 and you still get a kick ass speed. Sequential writes are the less important stat you'll need on a SSD for now, because you won't use those to put all your big data (music/videos).
Be sure to get the G2 as it is the second version of the drive, G1 is the first. They will support TRIM (Windows 7) and have a world class wear leveling algorithm.
