Loking forwards to the actual review. Looks like a oc monster, and much better thermals.
As for the 40nm gpus, latest word is May for the 4770, but its been quiet from nVidia, tho theres a few rumors of their 40nms coming maybe in June, but it wont be a top card either, as the 295 will be til we see the next gen cards, or DX11 compliant
PS, wont arrive til Q4 for those either, at least for nVidia, ATI may show sooner
