start digging in the mining sub-forums. I haven't done the research since my pc is the latest of the latest and I'm still dubbing what my future project is going to be... From what I understood, you should be able to dump one of the latest AMD cards into your mobo without issues. But once again, I did not do the proper research to confirm this, I just came across something and took a glimpse.
So once again do the research, the data is there in the forums, you just have to look for it. (being able to use a PCIe gen3 (3.0) would give great benifits, as they are a lot more powerful and cheaper. Since PCIe gen1 is so old, only cards you'll find is second hand, and then still, they just won't have that much GPU power, since they are 5+ years old)
Ok buddy, cheers for that. Looks like I'll be purchasing a new mobo so that I can reap the benefits of PCIe 3.0. Thanks everyone!!
Any more advice please do post
