However note this, in the support page of your mobo it can only take the X2-6000 that runs at 89W
The link of tigerdirect shows the following serial number
That is a 6000 of 125W (the majority of them are 125W and I never knew there was an 89W version)
(Edit... even tigerdirect shows it's the 125W version)
So... all in all, get the 5200, for the price, it's a fantastic deal.
