YOu should still be asking if the hdd is bottlenecking you, the question is, what do you do with it. Gaming, you might see faster load times, you probably won't though. Start up, if you do it once a day, or less, does it matter if its 40 or 65 seconds?
Where do you think you're bottlenecked is the first question, then you go and look at benchmarks of REAL WORLD applications and see if theres any difference, for most people most of the time, there won't be a significant difference. I'll be honest, my systems a HELL of a lot more responsive, i tend to unrar a lot of files a lot of the time and with my old hdd's that would/could cause a lot of hanging, you transfer a file, have some other app doing something in the background, click on the taskbar and something takes ages to open, those things are almost completely gone with ssd's.
Faster load, some things very much so, others theres no difference.
Synthetic benchmarks will convince you ssd's are 7000 times faster and you'll see no end of improvement, the reality is, they are massively faster, but most things only need a tiny bit more speed before they become bottlenecked elsewhere anyway.
An intel is streets ahead in some area's, yet game loads are identical to those of far slower ssd's, not much ahead of a decent 7200rpm drive.
if you can afford it, who cares anyway, get one, some things it will be nice for. But if you're expecting game load times to halve, you'll be dissappointed.
