This is the card I bought.

It's not overclocked right now. I'm running at 925 MHz.
It's in the right PCIe slot and it went through a proper burn in cycle at the shop before I picked it up.
Thanks for the info about Afterburner and power cycling. I have to admit my ignorance on much of this stuff. I am busily reading up on how to use Afterburner and GPU-Z and what all the numbers mean. Will try them out and see what they say.
Mobo bios is the most recent one. It was flashed on June 20th.
