Having some issues with a new set up. Example http://www.youtube.com/watch?v=rykZjhlu61E

I tried out LM 14 Mate/KDE In KDE if I installed the Restricted drivers then Open Arena worked good but Nexuiz was still like the video. I tried 12.10/11 13.1 - same results.

I have the set up listed below. I also have a second set up like this but with a A8-5600K CPU and AMD ram which is working good although it does have one of the glitches explained below.

76269 AMD A10-5800K APU Quad Core Processor Socket FM2 3.8GHZ 4MB 100W Retail Box

35507 Nmedia HTPC-5000B Desktop Media Centre Case mATX

I also get white pixels on the screen especially around images or window borders. I have something similar on the A8 system but not too noticeable.

Any ideas? My only other option is to take this box home and start swaping out parts and see what could be wrong.
