Hey I have an ASUS P7P55 WS SuperComputer motherboard, the one with the 5 pcie 16x slots. So I was wondering now that I'm building this thing, which slots are ideal for a 2 card crossfire setup? There are 2 blue. 2 black and 1 white.
This quote is from the ASUS product website from this product -"Besides, P7P55 WS SuperComputer provide you the fastest 2-Way SLI graphic performance when you install Geforce graphic cards in the two blue PCIe x16 lots which can work at 16 links"
So isn't the quote stating that in order to get x16 speeds on both slots, you have to utilize the BLUE slots?
I'm assuming that ASUS would have provided a relatively long CrossFireX bridge. Otherwise if your graphic card manufacturer or ASUS hasn't, then you will need to find a longer one. For the majority of graphic cards, there is not a noticeably difference between 16x/16x and 8x/8x. The HD 4870 X2, HD 5970 and possibly GTX 480 will be the only cards which would 'see' a noticeable performance decrease. For example with HD 5870s, there is less than a 5% performance difference in average.
