Question 3

Is the graphics card a GT740 or a GT740 GDDR5?

Accepted Answer

The label on the side of my machine says this : NVIDIA GeForce GT470 4GB. I have no idea if this answers your question or not  but that's what it says. I'm not a gamer; I'm a photographer and this is more that adequate for my needs. My most recent camera  shoots 16.1 megapixels per image. I was looking for reliability not the latest and greatest. There were no refurbished units like this available. I took that to mean this is a great computer from the factory the first time. The components have been in use for a long time and have proved themselves.  I personally think this is a great computer for those of us who don't buy a new machine every 6 months. Enough said.

Question 4
