So, I just ordered a 27" Apple LED Cinema Display today. Weeee! I know you're jealous, but that's not why I mention it. No, I have a question: Is gaming performance (noticeably) worse, when playing games on an external monitor? I have a 15" i7 MBP with 8GB RAM and GeForce GT 330M 512MB. There's of course a difference in resolution: 1680x1050 vs. 2560x1440 - about twice as many pixels. But will that result in the half amount of fps?
