I just found a new bench on the AMD W5000. The first I hear for:
Tested on an Intel Core i7-3770K Ivy Bridge Quad-Core CPU.
Near 58.59 at sw-02. I let you judge if it is an important step towards the V5900 that should be in the same range market (I found 53.23 data on that card on a less 3Ghz Xeon CPU). More data would be welcome to get a robust opinion.
I just regret there is no W4000. When buying the V4800, the perf/price was incredibly high.
