My buddy just switched from amd to nvidia and was selling his RX480 so I decided to buy it from him. Only to find out that my PC is so damn old that I don't think I can actually use the GFX card. I just need to know if 16xPCI 2.0 will cause issues in the long run since the rx480 requires PCI 3.0. I will be contacting xfx on Monday since they are not open at the moment anyways here is my setup. (I do also understand that my system will be severely bottle necked as well if I run this card.)
Thank you for that link theirs basically no difference in game performance other than 1-2fps changes. I think I might wait and see what xfx has to say on Monday before I make my decision though.
What about calling the motherboard manufactors. How big is your power supply and does it have the right power connector for the card. Those are my thoughts. I have an old supermicro server board C7X58 and my gigabyte RX 480. It seams to be running fine.
Bandwith of the PCI slot is not a problem at all. What you should worry about is the bottlenecking that you might get with that CPU if you're playing CPU intensive games or you're going for a low resolution and detail settings. My Q6600 struggled to keep up in MMO games, but was doing fine in games like CoD or driving simulators for example.
