I'd go with the nVidia. It will allow you access to GPU acceleration.
Of course. Thanks, Jim
While I agree with Jim, go for a nVidia card, the K3000m looks like overkill with the CPU chosen, i5-3320m. It would be a superb choice if you choose the i7-3840qm or even the 3940qm CPU and a lot more RAM.
The model you have chosen with the i5-3320m comes standard with only 4 GB RAM and that is far below what you would want. You want at least 16 but better 32 GB.
I'll look at moving up to the i-7 but I had already built in 16gb.
