Those hybrid drives while they gave a mild uptick to standard HDDs are not enough to compare with SSD. So let's ignore that.

16GB is nice, I have such (Lenovo y510p dual SLI, 16GB RAM, etc that cost 999.99USD) It's mostly not taxed so for everyday folk 8GB is my nod. Still if you can, why not?

Nod to the SSD. It's going to be very very nice.
