Hi all, wasn't too sure on which subforum to use based on the relevancy of so many components. I'm looking for some knowledge and advice on the subject of PCIe lanes. So I hear with P55 type motherboards, if you're using an SSD with full sata3 enabled, it bumps the video card slot from x16 to x8 lanes. I've read a little on the subject, and I'm looking for advice in my specific situation. I was planning on getting the following parts:
mobo - ASUS P7P55D-E LX LGA 1156 SATA 6Gb/s USB 3.0 ATX

ssd - Crucial RealSSD C300 2.5" 128GB SATA III (SSD)
http://www.newegg.com/Product/Product.aspx?Item=N82E16820148362
vidcard - MSI N460GTX CYCLONE GTX 460 1GB
http://www.newegg.com/Product/Product.aspx?Item=N82E16814127510
also an i5-760 cpu that I plan on doing some OCing with, aftermarket cooler and such.
I read the article here at
http://www.tomshardware.com/reviews/pcie-geforce-gtx-480-x16-x8-x4,2696-9.html
and it details an average 8% performance loss with a single gtx 480 when going from 16 to 8 lanes. Looks like the CPU isn't a bottleneck in a single card setup, thus the slight performance loss? What I'm wondering is, can I expect a similar performance loss with my gtx 460? Is it a significant performance loss? Are there p55 1156 socket mobos that don't have this lane switching bottleneck?
Thanks for your time.
