Sweet, thanks alot that should help much, however what are extenders/adaptors to make it fit?
An extender/adapter has got a 1x (or 2x or whatever x) connector on one end so you can plug it into your motherboard's slot. On the other end, it's either an open end slot, or a full 16x slot so you can fit your graphics card into it.
This then allows you to use those shorter 1x/2x slots for mining purposes since mining does not require the kind of bandwidth actual graphics would.
