Well, the manual is a good place to look at this or the BIOS of the RIVE has a PCIe lane simulator to tell you at what speed the lanes will be in different combinations....
Both your 690s wont be running X16 at the moment with all those things occupying the other lanes. If you want/need top bandwidth/speed you will need to leave out some things. Run 690s in first and third red slots and another device in the black slot 2B. Outputting the desktop is no work for the GPU so getting the first 690 to do that won't affect rendering performance.

Thanx 4 the Help guys!
Space is not an issue in my setup cause i have that kind of "james bond goldfinger nuclear bomb design" in a machine room (see pictures)
so i keep my gpus up in the air for cooling and connect them via extensions.
And the GTX 760 hold another 1000 Cuda Cores and since my Octane render scales Renderpower with
every Cuda it can get a hold of ... this 760 is another significant 11% Render Speed increase ... thats why i
just dont wanna drop it if i dont have to 😉
After installing Basic Win7 i got all the Cards working but two new issues:
1. My RAID on the Adaptec 5805 Controller shows really poor performance ... around 25% of the read an write speeds i had on my previous setup ... (the 8x PCIe Lane is unlikely to be the bottleneck innit?)
2. I get serious onscreen stuttering when im just surfin with Firefox or even in Fluidmark i get like 40 fps max (maybe still something wrong the way i set up the three gpu-cards)
hm ... ill keep testin ... if ya have an idea, please fire 😉
