New investment

[antares]

I am considering a new motherboard purchase in order to add more cards to the system.  I see various specs that say PCI-E X-16 slots and X-8. 

I am not sure what the X-?? means or if it affects mining.

Any suggestions or clarifications?

Any recommendations on motherboard specs to look for?

X is a prefix for *
the number behind that specifies the amount of lanes that are connected to the PCI Express bus.
x16 is usually used for graphics, as they need most of the bandwidth.
x1 x4 and x8 are usually used for generic devices.

Wow, just wow.
OP buys mining rig and hasn't even researched or understood the concept of difficulty levels before hand.

Fucking golf clap good sir.

 

This is what I did when I bought another 2 GPUs (5850s) to my PC (only had a 6850 be4), but I don't regret it, mining is still profitable with 0.9 Ghash/s.
