thats the thing w/ 24's you have to have card/s to handle them. I think gaming on 1920x1200 is awesome but my statement is kinda biased since I haven't gamed on anything lower other than a 1440x900. So I really wouldn't know how 1680 is compared to 1920. I myself am trying to sell my 24" for two 22" for studio work.
I was trying to sell it for $375 but if your interested and since your a member I guess I'd let it go for $330 since your in jersey it shouldn't be too much to ship since I'm in Mass. LMK if you want pics. Model info LG L246WP-BN
