I am finally approaching getting a MB with PCI-e
Yes, you read that right - I am losing (or going to lose) my PCI-e virginity.
And I have a question.
I have seen some boards marked as say s PCI-e 16x/8x8x. Now I am presuming that this means there are 16 lanes shared between the 2 PCI-e sockets, and if only 1 is used it gets all 16, but if both are filled they get 8 each.
Have I got this right?
A sub question - which is more geared towards graphics cards - is does the number of lanes actually make a real world difference?
If I have my above assumptions correct, the P8Z77 WS appears to have 32 lanes shared between 4 PCI-e 3.0 sockets, allowing for configurations of 16/16/0/0, 16/8/8/0 or 8/8/8/8. Where as the Z77 Sabertooth appears to have 16 lanes shared between 2 PCI-e 3.0 sockets allowing for 16/0 or 8/8 configurations.
Now here is the question - does it really make any difference?
Lets assume that the 2 boards are practically equal performance wise in every aspect apart from PCI-e (I haven't looked into the benchmarks so this may not be true - but lets assume for the time being).
now lets also assume I have 2 identical GFX cards - I will take the GTX 690 as an example as it is one of the most powerful out there.
If I install both of them - would there be any difference between a board that can only offer 8/8 to a board than can offer 16/16?
If not, how far away are we from the GFX cards needing more than x8?
Thank you.
