If you go to a 24in monitor, you'll have a 1920x1080 resolution and the stuff on the screen just looks smallish to me at the native resolution, so if I was going to go that high I would get a 27-30in.
If you're a heavy gamer, I definitely wouldn't get a 1920x1080 panel unless you're going to pair it with some serious graphics hardware. You'll get roughly 15-20% better performance (speaking in FPS) out of a 1680x1050 panel when running each at native resolution. On my 1900XTX 512MB card, this would make or break running at native resolution with AA and AF enabled for example. Of course, you have an 8800GTX so go for the 24in if you wish on that note 🙂.
