Best graphics card for laptop?

I've fixated on two laptops
1. ASUS G551JX with 2gb Nvidia 950M-16GB RAM-i7 3.6Ghz
2. Lenovo Y50 with 4gb Nvidia 850M- 8GB RAM-i7 3.5Ghz

I can't help but decide which graphics chipset is the better choice.

I'd probably go for the 950M since it's a newer chipset. But if you arn't using it for university study and it's just for at home use. I'd definitely recommend a custom desktop!

But yeah regarding your laptop, i'd go with the asus laptop. They are really good.

I know Asus makes good gaming laptops. Go with Asus. Those graphic card aren't really high end anyway so the additional 2GB VRAM in the 850 is probably not going to matter much.

I go with NvidiaGeForceGTX Titan X.It's a fastest and the finest single-GPU graphics card on the planet.
