"Can I replace the procesor i3 to i7?" için yanıtI was wondering how well the successful upgrades are doing after a few months. Are the machines still running well with no overheating problems? I am looking to do the same with my mid 2010 i3 iMac since the i7 870 prices are dropping like stones. Any updates especially around performance would be gratefully appreciated. Update: Thanks EnglandGreen I successfully switched the i3 550 processor for the i7 870 and dropped a Samsung 830 SSD in there as well for good measure. Machine is working perfectly with no issues. To anyone else considering the upgrade, I would wholeheartedly recommend it, the performance of the machine for encoding video etc. has doubled. It wasn't actually too difficult, on a scale of 1 to 10, with 10 being the hardest I would put it at about 4.
