Looking at the specs of this motherboard clicky under the expansion slots section there was the following
3 x PCI (32 bit)
1 x PCI-E x16 (x4 bandwidth)
2 x PCI-Express (x1)
1 x PCI-Express (x16 Graphics)
The bold stuff is what is confusing me, is the x4 bandwith better or worse etc. and what is it used for (GPU im guessing but dunno).
