pcgameshardware got 900MHz out of the "big" cooler, which kind of dents the theory that the cheaper cooler is better. Perhaps there's just a large variability in the amount of OC headroom in these chips? Would make sense seeing as these are the first chips on the new process.

Seems to be a good mid-end card.If it helps lower 4850 price even better....

CFX doesn't make sense with these, it'd cost around $300, for that price 4870 CF is superior on all counts.

4770CF has good scaling as usual, but I'd never go cf with 512mb cards

they'll b down to around $70-80 within the blink of an eye.

$150 CF sollution... IMO that compares positively to the 512mb 4870...

Why won't it support 3 and 4 way crossfire? It has two bridges..
Did someone try to do more than 2-way CF anyways?

How about a HD4770+HD4850 CF? Should be possible, right?

we also have to consider that the retail samples miss a phase on the power side so oc tests on most review samples are not to be trusted

I'd rather spend the extra 50 $ for cf-proof equipment to pick a 4890. :shrug:

Seems a few reviews got good idle power consumption. The majority horrible. Wonder if its just a driverfix with powerplay.

But considering that review samples aint like retail is hmm hmm. Other cooler and different phase as mentioned above.

Need retail testers :p:

If it is like in the xbitlabs one. Then I'll take one.

From Expreview regarding oc limit:

Quote:

If you want more, just open the Rivatuner.cfg, find “RV770 = 9440h-9443h,944Ch”, and add the ID “94B3h” after.

Which reviews use retail cards?

I have never used crossfire/SLI before, will my E8500 @ 4.25GHz be fine with 4770's?

Terrible idle consumption, GDDR5 strikes again... They should pack ATI Tray Tools with custom profiles with these cards :/

You should listen to yourself. It's ridiculous read those kind of posts here on XS. (same opinion about those posts in favor of Nvidia, intel, amd, microsoft, sony, watever)

I know quite a few well educated gamers that work in the "tech" field who still only buy nvidia based on misconceptions about ati drivers. These are software developers and server admins btw, and they still have no clue because they aren't what I'd consider "enthusiasts".

The points is not to say that every consumer feels one way or another but to share feedback from based on your experiences and conversations with others. The consumer bias favoring nvidia does exist whether you want to admit it or not. Have you ever heard someone who isn't an enthusiast say they only buy ati?

You greedy bit-tech guys, just can't say no to Nvidia's money, can't you? :down:
GTS250 anywhere to 50%-100% faster than 9800GT according to them
