I'm wouldn't say I doubt the truth of this statement, but like my OP says, I'm interested in numbers. If indeed it would bottleneck, I would like to know how much. Am I just going to lose a few frames, or is it going will my second card only be running at half power for instance?

Ideally something under $150, the cheaper the better.
I know some of the mobos with 3x PCI Express 2.0 slots have at least 2 of them running at 16x, but they usually cost more than I want to spend.
I'm going to be embarrassed to say I don't know the nomenclature that well, but my processor will be an i5 750 (is that LGA 1156 socket?).
