I must have missed that. I really doubt the difference between them is going to be significant. I personally prefer nvidia, but that is just personal preference.
Okay man, but I still want to know what kind of 7730M the laptop has. The Samsung site doesn't give much information so I was wondering about making someone who owns the computer to run some sort of program and tell me more specs.

Could this do the work?
Nah , both AMD 7730M & DDR3 640M are almost equivalent
i7 3630QM is 200MHz faster than i7 3632QM on both base clock and turbo boost clock
-> Samsung laptop win
Toss a coin to choose

Hnggg so hard to do this.
Question: is there a way to overclock the card so I can get It's maximum potential?
Yes , there are many software for GPU overclocking : MSI afterburner ,Sapphire TRIXX , EVGA Precision (fully tested on my GPU) , Nvidia Inspector ...
The only problem is the heat . Most multi-media laptop like that Samsung & Acer run really hot and maybe overheat with Dolphin
Hngggggggggggggg... I think I've made up my mind and I'm going for the Samsung. Hopefully I won't come back to this thread again asking for more advice.
See you in a few months with some questions about Dolphin, though. Thanks for everything!
