I think you're making a good decision here. I like 3 monitors, but any multi monitor setup is better than one IMO.
Any SSD will work with that board, and if it's S/ATA 6G then it gives you that future option to run with when the day comes you upgrade the motherboard for one that will surely have 6G. Also, in real world scenarios the separation of any SSD class is at most 20%. When we're talking 500MB/s or 250MB/s, that ain't a heck of a lot in reality. Some drive configs stand out in certain conditions then run lower in the pack at others; and then just trade blows through most rigorous tests for good reviews.
Take a peek at this:

I'd recommend the
120 OCZ Vertex3. Just a month ago I'd say to go for the Agility3, but for $10 difference at standard prices it's just worth the upgrade IMO. The Crucial is 128G and sounds a tad larger, but it's not at all because of the way the chipset uses the NAND. With the Crucial, you don't really get that 8G for usable space and is 120G by all means.
Just missed a 15% sale on OCZ drives. The V3 was 161.50 and the A3 was 145.95, with both having $20 MIR's. If you watch these drives, you'll probably see them drop a bit in price again at the egg, and still may have that $20 MIR. I picked up another V3 and it arrived with the latest firmware which was a bit of work to update on the prior drive.
