Well I tried running GTA IV on an Alienware laptop I payed $2300 in January 2009, Core2Duo 8600, 4gb ddr3 1066, 3870 in Crossfire X, 1920x1080 all textures, shadows, view distance on low, and the game chopped along at like 10-15FPS, were talking the BEST mobile platform had to offer, couldn't run a console game on low settings, yet a $300 Xbox runs flawlessly in that resolution. this was about a month or two after the PC release. GTA IVs horrible performance is most likely the reason why Red Dead and LA Noire didn't have a pc port, They all run on the same game engine... were talking about a game released in 2008, it should definitely NOT require a quad core processor to run.
