Looking into a new laptop, want your advice

Let me start of by thanking everyone who makes this project possible. I've played dolphin before on other computers and it's truly admirable what time and effort you've put into this.

I'm looking into buying a new laptop, I want a portable computer that I can play with good graphics on. There are mainly different computers that I'm considering:

First one is a is a Clevo P157S with i5-4200M and GTX 770M. That one I can afford now.

My other option is saving up some more money and buying either an Asus G750JH with i7 4700HQ and GTX 780M or a Clevo P375S with i7 4700MQ and 2 x 8970M in CrossFire.

I understand that Dolphin is more CPU- than GPU-demanding and that it doesn't support CrossFire. So my questions are:

How well will the three different computers manage to run games like Zelda SS, Mario Kart, Super Smash bros Brawl and Mario Galaxy? I suppose the Asus would do it best since it has the same CPU as the P375S but a better GPU setup for Dolphin. Will Dolphin ever support CrossFire? Is there any info on that?


Thanks again, and thanks for any help.
