What specs does a laptop need to run gmod and minecraft?

One. It must be windows 10, so you can get Minecraft.

Cheers 10 points please.

The guy above you is completely wrong, so lets start new. You want a laptop with a Quad Core CPU, AMD is fine but Intel is better but expensive. You need at least 4 gigs of RAM, I'll say 8 gigs is preferred. And you need a graphics card that has at least 1 gig of video ram, for this 2 gigs of video RAM will be preferred.
I recommend this one. If the Laptop has a Nvidia/GTI graphics card, you want the second number to be 4 or higher, such as 940 950 740 750 960 etc. For a AMD/Radeon card, look for the words R5, R7, R9 those will mean its newer and better.
