I'm newbie and decide to build system myself for the 1st time, I'm less aware of hardware terminology , So I hope friends here will help me!
ASUS P8Z77-V PREMIUM VS Gigabyte Intel Z77 Dual Thunderbolt ATX Motherboard
The problem is that Z77 motherboards are limited to just 16 PCIe lanes.
The ASUS board gets around this with a chip set that does some switching. This allows you to get x16 on 2 PCIe slots.
On the Gigabyte if you install the 2 GPUs the PCIe busses drop to x8.
I want someone to explain above 3 lines in detail...I cant understed terms and their meaning, I got this reply in other forum for building new machine, I can ask there itself but I just thought I wud ask here as its a specific hardware, motherboard forum.
