Right now im shopping around for a new monitor in the 23" range, so I'll probably be gaming at around 1920 x 1080 if I go that route. Obviously my slow CPU will bottleneck my GPU, but will it be obvious at this resolutioin? I don't play any particularly demanding games, mostly rfactor and every once in a while CoDWaW.
So, is a 23" monitor a good idea or should I look for a slightly smaller one?
