I just built a new PC with pretty solid specs, at least, more robust than most I've built in the past.
It's got a six-core AMD processor, 600watt power supply, 8GB RAM, etc.
I loaded up a fresh copy of the latest Ubuntu 11.10 and prepared to be blown away.
However, while it runs fine, I'm seeing frequent lag, where the mouse stops dragging momentarily, tabs freeze in the browser under both Firefox and Chromium (with only 4-5 tabs too, not a huge number of tabs), etc. The system monitor looks great, everything is almost at the baseline-- it's not like I'm loading the CPU or using tons of RAM.
Is there any common thing I'm overlooking that would affect this?
Specs, for those who want to know:
Motherboard: Gigabyte GA970A-UD3
Processor: (FX-6100)
RAM: Corsair 2x4GB DDRIII
Graphics: NVidia N550GTX-Ti (1GB RAM)
