I.must admit, that this is a rig, that I would also like to have, except the 680s.
You have everything you need. I also have veloci raptors and a samsung 830 series ssd. Played Arma 2 and clod on both storage types and I have a performance increase from the veloci raptor to the ssd, which I can really feel (also compared to a raid of 2 veloci raptors).
The 830 really does a great job in every day life behaviour. Much better than some other ssd of that time. The driving technology is great. I do not know, if the other chips are now performing as well as the samsung but when the 830 came out it was unbeatable in this price range because of its new concept. Just wanted to mention that. Perhaps you should read some recent reviews of tests, which are not just counting maximum read and write performances. I saw several big internet sides had really tested completely wrong! Be careful on eye washers.
