Get a cheap SSD just to start up windows faster, and a few other small programs would be an okay idea. I'd still rather just put extra money towards a better CPU or GPU, imo since I always go towards gaming.
@OP Could you suggest some good gaming monitors?
Budget? Size preferences?
Also, about the SSD debate.
I don't recommend getting a SSD unless you have a Z68 board with SRT Technology, that way it speeds up your whole HDD to speeds similar to that of a SSD, because of caching.
Boot seems like a waste of money when you could just spend a little more on a Z68 board and have it all.
Also, I never said Caviar Green was unreliable, but it's slow, and is considered the base model for their range. If you were to go WD, which I recommend because they make great hard drives, I'd at least go for a blue.
