Cant say its really reliable but seems reasonable to me.

These alleged benchmarks look poor for 4890 (just a tad faster 4870, 10% and less, and still running neck and neck with 260 core 16)
While these look very promising (on the order of 25% percent inprovement on 4870).

Why is the idle higher then the 4870? Something doesn't seem right... Hopefully this is just a fake review, because those idles don't look any better than the 4870.

sneaky bastards, now it's requiring me to login.
Ahhh. What did the link contain? Specs, benchmarks, both?

I should of kept the window open, but the most interesting aspect was 990mhz on the core with stock cooling.
EDIT: and was about 30% faster than the HD 4870 when at 990mhz.

Not bad.
I saved the results from NovaTech.

I'll have to wait for some reliable game benchmarks. But so far if this is any indication, it's not looking like a terribly compelling upgrade for my 4870 w/512 megs. Even though I'd love to move up to 1 gig.
Then again, if idle power consumption is significantly lower with similar load consumption it would be compelling, but all indications point to it using more than 4870.
