I have a SSD myself (the "Intel X25-M 80GB Sold-State Drive (SSD)" .. "like" frogboys just smaller (he might have another brand or w/e) .. i want the 160GB Intel One gah!!).
Anyways if you can afford it i say get one it will boost your system speed more than anything you do (as long as your system isn't poop lol).
But ... i found this crazy video on youtube of a guy taking 24 SSDs w/ 2 Quad-Cores ... and um ... yeah idk you just have to watch it.
Enjoy
