Does the screen look any better on the 27 inch than on the 21.5 inch? Like in brightness, color, etc. I know that the 27 inch is pretty high res with 2560X1440. I still am at a dead end for picking the 21.5 inch or 27 inch.
Configurations I am thinking about
21.5 inch $1299 model, 8GB RAM, 256GB Flash or 1TB Hard Drive
27 inch Standard $1799 model
Resolution doesn't matter. What matters is pixel density, measured in PPI.
Both 21.5" and 27" models have almost the same PPI (around 108-109 PPI).
Color-wise, doubt you'd notice anything.

Yeah, I am 95% sure that I am getting the 21.5 inch. The reason is because I just measured my desk and it is 30X20.5. That means that the 27 inch iMac would only leave me with 4 inches of free space, and the 21.5 inch would give me 10 inches of free space.
Still deciding but I am likely to choose the 21.5 inch.
And, how much faster would the NVIDIA GT 750M be in my uses compared to the Iris Pro? I would like to know that with my uses in mind.
Well, since the GT 650M is already faster than the IRIS in most aspects, you can be guaranteed that the GT 750M will be much faster than the IRIS in everything else.
