PPD Gets Worst With GTX770

[mykereid]

In an effort to boost my PPD, I just purchased and installed a GEForce GTX770 GPU. My CPU is CoreI5 over clocked and running stable at 4.6. Average PPD with the old GPU [Radeon HD6850] was about 14,500. FAHControl is reporting with the new GPU PPD of 13,777. I've read of others with the same card getting PPD of as much as 100,000. In fact, that's what I was expecting when I bought the new GPU. Any ideas what might be wrong, or what I can do to increase PPD with the GTX770?

Thanks.

Update: After spending $400 to increase my PPD, I have actually lost about 8,000. Current ETA on GPU slot is over 10 days.

Of course, I meant "worse", not worst.

Current Work Unit: ETA 10.20 days.

Came to realize it was because of the Nvidia driver. Seems the newer drivers produce quite a few less PPD than the older ones.
