Difference between K95 and K90?

[Xyger]

I've noticed the K95 tends to be cheaper than the k90 which makes no sense to me.

What are the main differences? I was originally going to be getting a k70 but managed to find a K95 for the price of a K70 (£100ish).

Can anyone enlighten me?

I believe the g-keys on the K90 aren't mechanical and you can't program the lighting on each individual key. The K95 is the newer, improved version for that reason.
