A:AnswerThere is not a simple answer for this. The device has a 3.8 GHz processor, which you can see that information under Specifications and then Key Specs on the Best Buy site. You can also find the information about how many cores it has under Processor in that same area from the Best Buy site. As far as the GPU is concerned, you will want to check the NVIDIA site for more information about specifics. You really want to base you systems off the requirements of the software you want to use and specifically the settings you want to run the software on.

It will depend mostly on what you want to do and the settings you are looking for.
