agreed with the 7950 option. $219 is a great price!
Still, you may not get quite that high OC, it varies. I have a 3L and I believe I got it at 1080 MHz core right now on 1.25V (stock) I had it a bit higher, like 1100-1150 in there, but it seemed kinda unstable after updating to 13.8 beta. Of course, it is a beta set, but I think an OC > 1150 on reasonable voltage is unusual for a 7950. If I were to guess an average, I would say 1050 to be more like it.
