I could go with a low end SSD now.
I have a post by Jak3676 bookmarked.

It basically recommended going for a decent SSD if you were putting the operating system on it.

My original plan was:
-- This Year: i7 920, 12gb new ram, x58 Motherboard.
-- Next Year: SSD (something like the generation 2 - Intel X25-M (34nm) 160GB $2.75 $440) and put Windows 7 & Warcraft on it.
-- After SSD Upgrade: Nvidia GT300 with lots of video ram & 2nd 30" monitor for dual monitor set up.

I've done the i7 / ram / motherboard upgrade this year.
Unfortunately wow randomly freezes, yesterday not even once in 12 hrs of play time, the day before every 15 minutes until I gave up on the game after 3-4 hrs of the crap.

The SSD I'd like, is supposed to be $440(us) from the linked thread.
I've seen it at my local computer store for $900(can) which even with the exchange rate and shipping it here, is rather exhorbitant.
Usually I do random warehouse work in the fall/winter/spring, but am on short term disability at the moment, so cash is rather tight.
I have very lucrative seasonal work from mid June through late September each year, and generally do upgrades then.

I could easily pick up a low end SSD now, but is it really worth it.. when I'm planning on a high end SSD in just over half a year?

Having visited every inn, in the game yesterday without any freeze issues, yet freezing around Honor Hold and Valgarde Keep constantly the day before (as I was adjusting macro's/hotkeys to use the auto FTL of ISBoxer instead of my cast everything at my target's target)... Well it's annoying when the freezes happen, and as far as I can tell, the same toons in the same area can freeze one day and be very smooth and problem free the next.
