GTA IV - Quad or Core i7 needed!
I am working on GTA IV Performance preview, here are some results with CPUs ... the first game which really needs Quad Core (Core i7 is best choice).

Physics engine Euphoria is very exacting for CPU performance, times of Dual Athlons and 512MB GFX in Solid Game Stations are over ...
Game is brutally limited by CPU, you can use Radeon HD4870 X2 or Tri-SLI, but fps will be the same like with single card. For higher performance of GFX you will need 4GHz Quad, better is 4GHz Core i7 :)
