21.5 or 23 for 1080p monitor?

I'm building a computer and I need a new monitor but I'm not sure if I should get a 21.5" or 23". Will text really be any smaller on a 21.5"?

I'll be doing only some mild gaming(minecraft, indie games). I'll also be working on 2D mobile game development.
I also experiment with 3D as well. I've made some 3D animations including things such as Minecraft and my own original series.

Also, 1 8gb stick or 2 4gb stick?

How hard is it for a single programmer to write a game that's not to complex, not to simple?

Indie developers make all this great games in such a short time maybe about 2-3 years, and make it across multiple systems. I've always wondered how they did it. How hard is it for an intermediate to advanced programmer to make a game like minecraft, castle crashers, super meatboy, binding of issac, blah, the old version of super Mario 64 ( I know it wasn't developed by a single developer) how long would it take them to make each game, and how hard?
