So as per title, looking to get another card, in my experience its easier to have one brand rather than try and make them place nice together.

This isn't SLI, I doubt anyone would suggest finding a 9800GTX, but if someone happens to know where an evga black pearl is going cheap

What do people reckon will provide a good bang for buck in matching block and card, its something I've not done for ages, so am very out of touch!
