  Nos, nem is rossz annyira a 8x/8x teljesítmény P67-nél.. A következőket találtam:

  "Now I should say a little something before I show you results of X58 vs. P67w/nf200. That is that the X58 platform has native support for SLI, it does it naturally. P67 is not meant to replace X58, especially not X58 SLI. P67 natively has 8 lanes of 5GT/S PCI-E 3.0 which goes into 16 lanes of 2.5GT/s PCI-E 2.0 which X58 has 36 lanes of PCI-E 2.0. You can see that P67 is in a huge disadvantage, so motherboard companies have taken it on their own to deliver platforms with the ability for 2-way SLI and 3-way SLI. Now while you can run 8x, 8x SLI, it is slightly better to run with full 16X per lane (not noticeable), and if you want to do 3 Way SLI you have to have at least 24-32 lanes. So the NF200 PCI-E Bridge is added. This bridge takes 16 lanes and turns them into 32. The NF200 is especially good at allocating the lanes correctly, but it has its drawbacks, most of which is its addition of latency to the PCI-E bus. "

  

  "The same thing here, graphics seems to increase with CPU speed, but at clock for clock the P67A-UD7 is faster than the X58A-UD5. But again the margin is a few points, for my standards it has to be 75-100 PTS or above on GPU score for it to be better. I would say that in most cases they are equal. "
