I used it in a desktop but that won't affect the performance or make a difference. Glad I could help.
Won't make a difference...
I actually laughed, that's VERY wrong.
The thing is there's a considerable performance gap between laptop and desktop parts. My ~5 year old desktop performs better than my high-end laptop i got this very morning. The thing is, in a desktop, there's the assumption there's a large area for heat to dissipate to with tons of fans everywhere, as well as a continual connection to any form of electricity. I think desktop CPUs use ~90 watts of power.
Laptops, on the other hand, have constraints such as a tiny area for heat dissipation and smaller fans. They also have to be able to work off of a battery. Where a laptop can make four hours of battery life, a desktop with the same battery would't last twenty minutes. The simple fact is, laptops are designed to save power, and desktops can consume close to 200 watts while idle. There is a huge performance gap, and although with every generation the gap closes, it's still very large.
If anything, look for dedicated GPUs. Post links to whatever you find that looks good and I'll make sure for you it'll play. MineCraft like you want.
