22" or 24" lcd with eVGA 8800 GTX 768 mb card

An 8800GTX will be able to run any RPG at a 24" monitors standard resolution of 1920x1600.
If you play more power hungry games, then just stick with the 22" @1680x1050

If all you play is RPGs and watch movies go for and hdcp compliant 24"

helios2052......it's 1920x1200

Not all MMORPGs are WoW.

You will have troubles driving 1920x1600 in AOC with that card, or any single card for that matter. You don't have to run such games at native resolution though.

both lotro and AoC would run better on the 22", most older mmorpgs will run fine on the bigger screens with the 8800gtx. Im pretty sure I ran WoW at 2048x1536 on a single 8800gtx when I was playing it.

Its worth noting that you will get a better image quality out of a 20" panel than 22" or 24" from the same range, due to smaller pixels \ higher pixel density. Smaller pixels reduces the need for AA.

Some people suggest sitting further away to blur away the effects of the larger pixels which of course reduces the effective screen size as well... By the same token why bother paying out for a bigger monitor when you can just sit closer to the smaller monitor to get the same effect

I set up a workarea for good ergonomics and comfort, and get my original image looking as good as possible.

Personally I prefer to get the native image as beautifull as possible and set up my seating and desk area for good ergonomics...

With an 8800GTX this "budget computer" would have more GPU power than the 360. Paired with a 24" LCD, and cheaper games, you may want to rethink that a bit. I can tell ya COD4 at 1920x1200 4xaa/16xaf and max details is might nice looking. If your buds are all on live, that's different.
