I've noticed since I got my E6600 in that for gaming etc... it's been great... it also runs very cool 20 degrees C under normal load. Although when I pop out into windowed mode while running a game such as DDO it's like someone threw a wrench in the gears transition to other apps is slow even freezish, and web surfing is sluggish. My Laptop has an AMD Duo Core 4400+ and I never experenced these issues.... I could be using bit comet converting with PSP 9, surfing the web and windowed in game and nothing ran particularly sluggish. I won't go into a major battle in game, but I could cruise around shops and town without issues. Here's the specs of the rest of my system if that sheds any insight.
