F@H with ATI 7750

I am getting some folding happening again. I have a decent work computer with a i7 3770

I also have decided to put my home computer to use. I have an old AMD Phenom 2 at 3GHz with a ATI HD 7770. What PPD should I expect from the HD7770? It says it is good for about 3000-4000 PPD which don't really seem worth the power cost.

I have been reading that it is best to have a few WUs running on the card? It also takes away a core from the CPU to GPU fold

What are your recommendations for this set up?

Sorry it is a ATI 7750.

On a side note what PPD do you think a i7-3770 should get. I'm getting stats of 4000-17000? Inconsistent WU?

Here is a screen capture of my current WU on the i7-3770 @3.4Ghz (system says at 3.64Ghz)

I thought it would produce better results than what has been seen

Okay after keeping an eye on the work computer via VNC I have found that if I am not logged into the computer it decreases output by around 2/3.

The computer runs Windows 8 and I have the power options set to full. Does Dell potentiall put settings in the BIOS or something? Can't think of why it slows down when I am not using it?
