Nvidia graphic cards: help to choose!

Hi.

I am buying a new laptop, and I need some input on the graphics.
I will mostly using the computer for 3D-modelling in programs as 3ds max, maya, autocad etc. My husband will probably use it for gaming now and then.
I am going for i7 3840QM processor, 32 GB ram, and SSD drive, but what about the graphic card?

I am considering Nvidia Quadro K2000m 2GB, K3000m 2GB and GeForce GTX680M 4GB.

I know quadro is a typical card for 3d, but isnt that about to change? I have heard somewhere that GTX680M will work fine with the newest 3ds max software. And what about the size of the card? How much does the size of the card matters? 2gb vs. 4gb

I am not an expert on this, and would really appreciate som help!

Thanks.

 

If you're working with professional applications like 3DSMax, Maya, AutoCAD, etc., it's absolutely no question: GeForce 6xxM cards are a no-go. You should only be looking at professional GPUs, such as the Quadro line or the FirePro line. Actually, it's the opposite of what you describe: CUDA performance, OpenCL/GL performance is gimped on the 6xxM cards (in comparison to the previous 5xxM generation), and the 7xxM isn't looking much better. This is because nVidia wanted to heavily optimized for gaming (at expense of professional performance) and partly because nVidia wants to steer professional users to their more profitable Quadro line anyway.

To put this into a car analogy, think of a Corvette (6xxM) and a F-350 (Quadro). Both are pretty powerful cards, but one's meant for raw speed (gaming) and the other is meant for torque and towing power (professional stuff). Which one would be better suited to tow a heavy trailer load?

 

Kuroi has it dead on. the 6xxm cards are EXTREMLY weak in anything with OpenCL and FP64. in MAYA and some other autodesk apps this can translate into a 200-800% speed difference.

if his gaming is priority and you don't mind waiting for MAYA to render roughly 1/8 as fast ....... go 680m
if the pro level apps you listed are priority get the biggest Quadro or FirePro card you can get. what system are you looking at for a render / 3D station and of the cards listed go K3000m

Kuroi ... the 7xxm are as bad as the 600's FYI

 

Thanks for your input!
You are absolutely right, I will go for the Quadro K3000m.
