Ugh. You guys have no idea how frustrating this is.
I don't even know why I even got myself thinking that AMD would fix their DX11 issues with Polaris. They were advertising some sort of new "DX11 command center" or a revised front end system that would dramatically lower the inherent DX11 overhead of GCN. The fact that they haven't fixed it means that the RX 480 might look decent on reviewer's i7-K powered test rigs but it will be poor in the average guy's i3 rig. This also probably means that Polaris drivers for DX11 are single threaded, which is going to add on to the hurt for people using older processors such as Sandy Bridge or Vishera. Way to go AMD.
Speak for yourself, man. I have a 380x which is self admittedly not a whole lot faster than a 380 4GB and I have next to no desire to "upgrade" to this card. Its only around 50-60% faster which makes it a tough sell for people who got 380s as late as a year ago. I've seen other members in this thread with a 7970 and a 280x express disappointment in the 480 and how they are going to stay with their cards.
