Hi, @ABCellars I got much faster boot times but that's because I primarily did upgrade because of SSD installation. I installed Intel SSD 510 250 GB as well so boot time is now just couple of seconds. http://imageshack.us/photo/my-images/802/screencapturece.png/ @Aman Patel Here are some benchmarks. I don't have XBench but you can see here Cinebench and Geekbench. http://imageshack.us/photo/my-images/20/screencapture2lh.png/ http://imageshack.us/photo/my-images/703/screencapture1i.png/ PS: OK, I downloaded XBench as well and I realized that it doesn't work under Lion... It hangs on Thread Test... Here is screenshot of test completed but without Thread component... http://imageshack.us/photo/my-images/856/screencapture3r.png/

Hi, I used regluar i7-2600, not unlocked "K" SKU. So, it should be "BX80623I72600". And now, as I'm using this setup for a week, I can just say that there is not difference in system behaviour. So, system fans are not spinning faster, machine is not noisier, it's 100% stable system... iStat dashboard widget says that CPU temp right now is 43C (CPU fan 938 RPM). Simply, system works as it's supposed to work. Unfortunately, similar applies for system speed - it's hard to notice big difference if you're "casual user" of computer. PS: Before I put new CPU instead of old-one I changed thermal paste - I used Artic Silver thermal compound (2-3 eur/package).
