Thanks. I should have posted this before, but the first card is my new 7900GT that eVGA sent as a replacement for the second one I listed which melted on me. I was just wondering if eVGA shipped me a worse card but since they are so close in comparison, I didn't think either one was inferior to the other.
However, I would try to overclock it but my Temperature Control in the nVidia Control Panel crashes on me every time I try to view it. So, until I can monitor the Temperature on my GPU, extreme overclocking is out of the question.
