when installing hd7770 graphic card on gigabyte b75m d3h motherboard it is blocking one of the two pcie X1 slot.now,the second pcie X1 slot is absolutely adjacent to the graphic card.i have three questions.whether if i install a wifi network pcie card on the second slot.will it block the airflow of my graphic card? second is if i used the second pcie express x16 slot for wifi network card will it affect the performance of my graphic card. third is should i use the second pcie x16 slot for the graphic card and use the first pcie x1 slot for my wifi network card? b75m d3h motherboard has pcie x16 3.0 slots.

1) If the network card does not block the GPU fan, then you are OK. 2) you can use the pciex16 for the network card, but it will take some of its PCIe lanes away. Then it will affect the graphic card's performance, but it maybe not much. 3) If you use the 2nd pciex16 slot, the GPU will run at x4 instead of x16.
Here is the review for the GPU in pciex16, x8,x4 performance. http://www.tomshardware.com/reviews/pci-express-scaling... So you are better to use the 2nd pciex16 for the network card.
