Servus TPU Forums! I'm upgrading the CPU of my T500 ThinkPad soon and I just wanted to ask yall what I can expect. (Full system specs under my profile) I currently have a Core 2 Duo P8600 3MB L2 @ 2.40GHz. The T9900 has 6MB L2 and runs at 3.06GHz. Im using a customized full copper heat sink. What is the T9900 comparable to? Does it get anywhere close to i3 performance? Is it comparable to a mobile 2.20GHz i3? Also - I play a lot of games on the T500 and one of them is GTA IV. I get 40-50 FPS on ALL LOWEST 800x480. I can go to 1280x800 (20-30FPS) but I prefer frame rate over looks. While playing GTA IV for example task manager tells me that both cores are utilized around %95. Does that mean the the CPU is the bottleneck? Can I expect a increase in frame rates after the upgrade? Thanks pals!
