Im exactly the same, in fact I become angry at people who run without AA. I refuse to play games with less than 4xAA. Aliasing is extremely annoying.
In fact, Im very hesitant to buy a screen larger than 17" because its more visible the larger it is. I used to have 21", that was torture.

I can't say I've ever even noticed. I guess that shows how important the graphics are to me.
