Last fall I upgraded from an OC'd Q9400 system to a stock speed Ivy Bridge 3570k system. Didn't see much of a boost in GPU heavy games or OS performance, CPU heavy games got a big boost though. Guild Wars 2 literally doubled in FPS for example. Strategy games like Galciv2 and Civ5 were much quicker in calculating AI turns on big maps. Sins of a Solar Empire ran better with multiple AI's in play. But with the direction the market is going I probably won't need a new CPU for years, its all about lowering TDP and improving integrated graphics for the mobile market now. Bah! Flimshaw!
