Hey I have a question: I will be getting either the 21.5-inch: 2.9GHz or 27-inch: 2.9GHz The 27inch would only cost about 250 more because of discounts. My question is how much better is the NVIDIA GeForce GTX 660M than the NVIDIA GeForce GT 650M? Will the extra pixels on the 27inch mean the 21inch will perform better? And which would you go for? Thanks for your help in advance! ---------- I'd really like an answer from people who know about graphics. I need to make a decision very soon. ---------- Please guys.
