You'll have to deside by yourself:
Nvidia:

Ati:

I still prefer Nvidia!
Nvidia also has PhysX, PureVideo and CUDA.
Ati has the same DirectX, etc.
Ati has more GigaFlops, etc (Nvidia = 73 GigaFlops, Ati = 360 - 520 GigaFlops).
But Nvidia has a higher processor clock/engine clock speed (Nvidia = 1150 Mhz, Ati = 450 - 650 Mhz).
Nvidia supports higher OpenGL (Nvidia = 4.1, Ati = 3.2)
Ati supports 3D, but Nvidia delivers 3D.
I'm still prefering the Nvidia!
I have seen a lot of laptops with a Ati graphics card fail, but the ones with Nvidia kept working.
The drivers and software for Nvidia are way more easier to get, than the ones for Ati.
Also Nvidia software is more userfriendly than Ati's.
Adobe works best on Nvidia, not on Ati
And as I said, the Ati will be better for gaming while the Nvidia has better picture quality due to it's PureVideo HD technology!
And both cards are in the same class, according to notebookcheck.net.
The Nvidia one is indeed lower, but it doesn't mean it performs extremely worse.
The difference is relatively small, because they are still in the same class and not in different classes.
And can't you guys read???
I wrote this: "Thus Ati is better if you are doing games that need a lot of system power."
Ati is better for heavy gaming!
Nvidia needs help from other components, Ati doesn't.
That's why Ati is better for gaming and Nvidia is better for image quality and movies.
I didn't say Ati is worse!
I only said that adjusting the settings is harder and more confusing!
Nvidia is more userfriendly and the settings are easier to adjust.
The reason why I prefer Nvidia:
You don't have a laptop just for gaming, you are also going to use it for other things as well.
Think about watching movies, listening to music, etc.
What you want is a proper CPU (not the cheapest of the Intel i series), so a i5 is better (it has 0.2 more Ghz, it doesn't seem much but multiply it by 4 and you have 0.8 Ghz more in total compared to the i3. And that makes a small difference).
But you also want to watch movies in a proper quality without lag (watch this video to see what PureVideo can do: http
/youtu.be/XITHbsUUlYI. The video doesn't lie, because I have a graphics card (the 4 year old 8400M G) with PureVideo and everything you see in the video is true).
If you want to watch 3D, Ati does support it but Nvidia is build for it.
If you need a longer battery life, Nvidia Optimus technology can help you with that.
Windows has different power settings, but Optimus technology makes sure that when you are doing nothing the graphics card is in idle and when it's needed the graphics card is delivering performance.
Nvidia also takes care of the realism of the games (Nvidia PhysX).
Make your own choice!
I prefer Nvidia, because of it's quality improvement technology and also for the gaming realism technology.
But Ati is still a gaming card, and will beat Nvidia with gaming (but not with watching movies, because Nvidia can even make a 360p movie look good).
I didn't say Ati is a bad card, I didn't say Nvidia is a bad card.
I just gave my opinion on what to choose and about what I prefer.
Ati is bought by AMD, I don't know the reason why but I know it happend.
So, if you need drivers you'll have to search through the (in my opinion) confusing AMD site.
Nvidia is able to keep standing on it's own legs, because Nvidia isn't bought by a other company yet (I hope that it is never going to happen at all, but you never know in these times).
I don't care about the opinion of others, because they have their opinion and I have mine.
Everybody has the right to say what they think is best!
I give my opinion and you give yours, that's how it works.
The choice of the graphics card is up to you!
