The 3570 is a pretty new chip. With that in mind, I'm not sure exactly what you are asking. I suppose it will be around for a few years (at least as long as your quad core extreme). I've never been one for SSDs (outside of laptop use--for the extended battery life). Why would you want one? They seem kind of prone to failure.
SSD's have rarely been prone to failure since there early days. The tech has come along way and they are, id say, no more prone to failure than a regular drive providing they are set up correctly.
Personally i think SSD's are one of the best investments to make into a new computer, getting a good quality one on a 6gb sata 3 connection and you'll never look back.
