Hi all, first post. I recently got a stellar deal on a 2010 iMac in practically new condition. I was orginially opting for an i5 but I couldnt pass this up. Anyway, speed is great I used PhotoShop, LogicPro, etc no problem. However the one thing I've noticed is my video playback being very slow to buffer. I don't seem to have WiFi issues with an of my other deviced, so any hints on to how I can speed this up?
