Good time to buy a gaming laptop?

I've currently got a £1500 budget for a gaming laptop. Mostly looking at PCspecialist and getting one with a 980m gtx. Obviously I don't want to rush things so I wanted to ask whether this is a good time to buy a new laptop or should I wait a bit longer for new graphic cards? If so when are new ones out? Are the current ones going out of date soon? Also mostly looking at Nvidia as I've had bad experiences with AMD.

Thanks!
