Will a PCI sound card limit SLI options? Will FX-8350 bottleneck high end cards?

Hi guys, I'm wondering if using a PCI sound card with an ASUS Sabertooth 990FX/GEN3 will block any of the lanes for installing three 770/780 sized GPUs or if it affects how much bandwidth is available for the separate PCIe lanes?

For example, is 3-way SLI/CFX w/ a soundcard possible or would I have to sacrifice the sound card for a third GPU option?

Also, will I save an extra PCIe lane to use in the future by going with a dual GPU like a 690 instead of 2x 680s, or will it leave me with too less bandwidth to utilize the extra lane that it wouldn't make any difference?

Also, will using an SSD PCIe Adapter like the Apricorn Velocity Solo X2 increase SSD performance on a motherboard that already has SATA 6Gb/s?

Also, at what point would I be spending too much on GPU that would I begin to not see increased framerates in gaming on a 200$ FX-8350 CPU compared to higher end Intel CPUs? Is it worth throwing out the 200$ AMD MB I already have for an Intel CPU and MB if I'm already decided on spending more than 1K on GPUs? I plan on 5760x1080 and/or 120hz gaming.

I have that MOBO and in order to do 3-way SLI you could still fit the sound card into the black colored PCIe lane. Having a sound card will not affect your GPU performance, and the only way an FX-8350 would bottleneck GPUs is if you had a 3-way GTX TITAN array. Personally I see no need to get a PCIe SSD adapter as current speeds are enough for my needs so I can't really help with that.
