Single HD 4870 X2 versus Two HD 4870s on P45

Tweaktown published a comparison of the new HD 4870 X2 versus two HD 4870 cards on P45 motherboard.
Quote from the review: "Just the other day, I was talking about how the HD 4870 X2 is a great card for P45 users. When I tested HD 4870 in CrossFire a few months back on both the P45 and X48, we noticed that the x8 / x8 configuration present on the P45 actually gave us a bit of a hit in performance. So, what we’re going to do today is chuck a pair of Sapphire HD 4870s into a P45 board and do a bunch of tests. We’re then going to pull those two cards out and stick in a single HD 4870 X2. We will run the same tests and proceed to compare. Since we’ve already looked at the cards themselves, we’re just going to get stuck straight into the benchmarking side of things. Let’s begin by taking a quick look at our testbed we’re using today, before getting stuck straight into the benchmarks."
