Quick follow-up, I ran some tests a while ago of various SSDs on a
P55/SATA2 platform. Although
not SATA3, they show what the previous poster confirms, that having an SSD of
some kind is what
matters, ie. in the real-world tests, like starting up a game, the spread between different SSD models
is pretty narrow. I plan on running the tests on a native Intel-based SATA3 platform later, not had
time yet.
I agree about Samsung for reliability. Although I have more than 30 OCZ models and have never
had a problem with any of them, Samsung has earned a strong reputation, though these days I
doubt there's much of a reliability difference between the various top-end models such as the
840 Pro, Vertex4, Vector, etc. I'd be happy with any of them in a top-spec build.
What I do like about Samsung units though is that, for some reason, they seem to be particularly
good at maintaining consistent steady-state performance, eg. here's an HDTech read test on
my 250GB 840 (5GHz 2700K, ASUS M4E) after several months of normal use:

Quite astonishing. None of my OCZ or other models behave in that way, not even the Vector,
and this is just with the normal 840 250GB!
So yes, you'd be fine with the standard 840, but if you have the budget, get the 250GB instead.
