I bought the ASUS M4A89GTD PRO/USB3 motherboard a while back, but I am not understanding this motherboard,.....
It has 2 x PCI-E 2.0 Graphics slots(16X) but I have to plug in my VGA switch Card in the top PCI-E 2.0 slot so that my graphics card(in the bottom slot) will run on PCI-E 2.0 16X. Apparently if I plug something except for the VGA Switch card into the top slot my Graphics Card speed will fall to 8x speed.
My problem is this, I would like to buy the Asus Xonar Xense Soundcard which is PCI-E 1X and will thus fit in the top PCI-E 2.0 slot, but will this pull my Graphics performance down to 8x speed in stead of 16x or not??
I would like to have the sound card but will rather leaf the sound card than to lose graphics performance, am I making an mistake to think that my PCI-E 2.0 slot speed will drop to 8x, is maybe only applicable to SLI and Crosfire?? But then why the VGA switch card??
