Great review. And great card, although I have to agree with many people here that is not what I was expecting performance wise. The power consumption is excelent though and I do like that a lot, it literally destroys everything else in perf/watt.
But it has me scratching my head as to why is not faster than the 4870 X2. Their specs are the same more or less, but the HD5870 runs 100 Mhz faster and doesn't suffer any Crossfire scaling problem. I would like to see a 2GB HD5870 benched, to see if that is the problem. Otherwise I can only think about the dispatch processor being slow to handle all those SPs, something that some experts said it was one minor flaw in GT200 chips too. A better optimization can fix that to an extent, so hypothetically we can expect significant improvements with futre driver releases. More than what is normal or average I mean. GT200 did increase performance more than what was usual with other cards.
PD. Wizzard, you did posted your review at 6:00:01 AM CET as you said.
