I finally decided to get some Intel hardware.

cpus=1 doesn't cut it for me. I have to close every application to run 720p smoothly and I have a lot of 1080p content (which barely runs obviously). Don't want to go back to windows so this was the only option with no working solution for this bug.

Here's what I ordered

Arctic Cooling Freezer 7 Pro LGA775 2500RPM 45CFM
G.SKILL F2-8500CL5D-4GBPK PC2-8500 4GB 2X2GB DDR2-1066 CL5-5-5-15 240PIN Dual Channel Memory Kit
