Problems with Thunderbolt Display

[Mavve]

2.4 GHz i7 MBP 8.2
16 GB RAM
New SSD, HDD in DVDtray

10.9 b4

When connecting TB 27" display after a while CPU is rocketing up to 5-600%

Anyone familiar with this problem?

Horaaaayyyy, I'm the only one here with this problem...

Today the MacBook bluescreened on me when I tried the TB display
Has anything else caused known trouble with TB display in 10.9? Apps, printers, other devices?

Can HD in DVDtray cause this?

And I know, its a beta.
