I don't know if it's my imagination or what, or if I am remembering things wrong, but my iMac(2,8 GHz, 4 Gigs of Ram, 8800 GS) feels kinda slow sometimes. Imovie 08 is very slow, sometimes during Youtube videos it will stutter for a while. Clicking on a song to play in Itunes sometimes takes 5 seconds to start playing like it needs to think for me to pause it or stop it, and this is without covers being shown. I feel that WoW runs not so good anymore either, but there are some bugs and graphics upgrades since I got it I guess, but still. When I got the machine I could run countless HD Movies on top of each other other with no stuttering at all. It just seems slower. Can I do a hardware test by myself to check if everything is up to par? I did the windows aero test and got 5.7 I think. CPU got the lowest score. Ram and Harddrive was good, so I dont know if those were the problem. My local mac retailer is very unfriendly, and don't seem bothered to help. They really couldn't care less, which is annoying. It's not apples fault, they are just a mac fan shop that became the official mac chain in my country(Humac). So I don't know what to do. I went into disk utility and tried to repair my drives, don't think it made a difference. Maybe I am just crazy though... can I do a test in vista to see everything is working? would a 3DMark 06 test give me beneficial results to the power? or could I have gotten a virus on the mac side?(recently installed Vista. OSX feels more sluggish now).
