Get the Samsung 840 Pro instead. (No cheap TLC NAND, Longer warranty, faster, doesn't cost much more.)
In-fact what's your current system?
I'm kinda pushing the limits of what I am willing to spend on this upgrade already TBH, is the pro series really worth the extra $70NZD? Write speed isn't that important to me TBH especially coming from a mechanical HDD, and the random access difference shouldn't have a huge impact. But the much longer life of MLC is a nice advantage I have to admit I guess it might be worth biting the bullet for that.
Currently running off a Phenom II 955 (aparently I got a bad batch or something because it does not like to be overclocked) and a cheap ASUS M4A87TD/USB3 Mobo, plus 8GB of cheap 1333 DDR3.
I should mention I plan on replacing my 560 Ti (@900MHz) next year some time before The Witcher 3 hits. I would like to think that Maxwell will drop in time, fingers crossed anyway. The recent Nvidia driver bullshit has kinda made me consider jumping back to AMD but Witcher 3 makes me want to stick with Nvidia lol, I am such a sucker.
