The 830 is my first choice. It's also a few bucks cheaper than the 840. But my local computer hardware store run out of stock on the 830.
And no, I'll put it on even if I have the 840 (not pro). I have yet to see a gaming laptop at uni, let alone one with an SSD on it.
There is this thing going on where the guys I know at uni are like "I have an ultrabook/MBA and I don't have to keep my laptop plugged in."
My response was (with my old laptop that is), "Your laptop can't run Skyrim on high.", then load up Skyrim.
Now with the GX60, I'll run Unigine benchmark on ultra and crystal disk mark every tutorial
So yes, SSD sticker is definitely on the laptop.
