I just recently (yesterday) updated my Nvidia driver because I wanted to start mining bitcoins. After downloading the driver and installing it, and running the miner, I get a popup notifying me that there were no OpenCL devices found. I have restarted my computer and whatnot.
I have an Nvidia GeForce GTX 465
Also,
How many MHs would I get on my i7 930 @ 2.8GHz
thanks
