I don't game at all, but my wife edits pictures for her home photography business. What are the, if any, advantages to the NVIDIA GeForce GTX 680MX 2GB GDDR5 vs. NVIDIA GeForce GTX 675MX 1GB GDDR5 as it pertains to photo editing. I did order the high end 27" with 1TB fusion and 16 GB RAM. I got the 675MX graphics card.
