very good and complete review, thank you. I am dissapointed by the 4890 as others said before, it eats watts like there's no tomorrow, noisy, and really, my opinion is they should have put it out quietly like the 4770 (which i truly like, it beats my 4850 in some tests grrr...) not with that much advertisement. i know people will contradict me, but performance wise, the 4890 looks really like an overclocked 4870 and nothing more.
When you look at this chip from the perspective of gtx 275 (which is like the best deal in my eyes now as it outperformed gtx 280 in many cases and will give you a truly HD gaming experience 'till next gen at the same price as a 4890, +CUDA, +Physx, winner at all fronts) it just seems such a bad move by ATI.
Now all cards have it and no one talks about it. Don't get me wrong, I'm an AMD guy, from the K6 3D period onwards. I really wish them all the best, the prices on the IT market depend on their products very much. I just feel that this time gfx 275 did it's job against HD4890. if the price would go down for 4890 to 200-210... that would be a different story.
