do processors make a difference to fps ingame?
Not as much as the performance of the graphics chip, because that is what does all the heavy lifting as far as rending on the screen. Intel HD 3000, 4000 etc., only graphics is really poor as it's only CPU based.
It's really not advised to use a expensive Mac laptop for 3D gaming, especially the Retina because it's sealed.
The reason is the hotter the Mac gets, the more air it has to draw in to cool the machine, which more vent clogging dust it inhales which overheats the machine and tends to shorten it's lifespan. Also using the inferior bubble membrane keyboard too much tends to wear it out.
If you want to 3D game, either buy a dedicated Windows 7 3D gaming tower so you can clean the dust out, upgrade the graphics card and be compatible with everyone else, use tougher keyboards (clicky clack types) and so forth, or if your budget can't do that and the Mac, then a PS3 or a XBox.
3D games are always improving, new ones come out and require better video cards, you can't upgrade a video card in a laptop. So you won't be playing for long.
OS X changes every year, so it breaks games. Windows 7 will remain so until 2020.

TigerDirect will help you build a gaming PC, and with this video card you'll likely never have to upgrade it. 😁
