Hi all! So, I own a mid 2007 iMac with the aforementioned ATI Mobility Radeon HD 2600 "Pro" (really an underclocked XT). I use the machine for general computing, some light Final Cut / iMovie rendering, recording, and light gaming. I am considering either a new Macbook Air or a Macbook Pro 13" with an SSD and I am confident that most functions will be dramatically faster on those machines.... however, I have some questions about the graphic subsystems. I have been seeing Cinebench results and other benchmarks putting the integrated Intel HD 4000 graphics around twice as fast as my ATI. I find this startling to believe. Perhaps I am jaded from the dark days of the GMA series. Anyways, are these accurate results? My principle that when upgrading that the new system should be at least twice as fast in every way, so this intrigues me. My main concern is the light gaming I do. My big titles are Team Fortress 2, Counter Strike: Source, the Portal series, Civ IV. Would these games run faster on the new graphics systems? How would this system fare with the upcoming Counter Strike: Global Offensive? Or should I just wait for Haswell? Thanks all for your help.
