i was wondering if i had gotten a riser for my graphics cards if they would mine ether better then say just having a gpu installed in a x16slot and a x8 slot?
also does anyone have any they recommended? preferably on newegg as i get free ship there.
x1 to x16 risers can help you be more universal, since you can use any physical PCIe slot for mining, however, they are not "better" for mining performance. Additionally, using risers can give you more flexibility with card placement (and thus cooling) outside of your case.
PCIe bandwidth does not matter much for mining on the vast majority of algorithms, just make sure that you use a powered riser if your graphics card needs one (most are better off with one), since using an unpowered riser can cause damage to your motherboard if you aren't careful. (One low-end card, like an HD 7770 is probably fine with an unpowered riser, but multiple cards or more powerful ones can cause problems.)
