thank you both. but does an old PCIe x16 reduce GPU performance. some say it does, i've seen fps tests that show the same. Is this comepletly up to a certain GPU?
i am now rethinking for a gtx970 as it goes for more than 100 less than a gtx 1060gb. you think it's worth it?
The reduced bandwidth of older PCIe x16 revisions does not affect mining. While it may be a concern for other purposes, such as gaming, mining is a different story. (After all, nearly everyone with a dedicated rig connects graphics cards to PCIe x1 slots with risers.)
