It isn't practical, but when you buy one all your n00bz0r friends think your are 1337 :DQuote:

Finally, Techreport's review
http://techreport.com/articles.x/16820
Why would you want to crossfire different model cards anyway? ATI have enough driver problems with regular crossfire (but getting better), crossfiring different models is just asking for trouble.
perhaps triple and quad crossfire disabled over stuttering concerns.

The 4770's will be cheapest solution of the lot. Heat won't be a problem since i would be watercooling them :)
Radeon HD 4770 Media Edition VS Retail Edition
http://en.expreview.com/2009/04/30/r...html#more-3356Quote:
Besides Radeon HD 4770 retail edition, AMD has actually prepared another edition for media’s test. The two editions look quite differently, but perform almost equally. As you can see below, the media edition is designed elegantly with a more effective cooler.
The media edition brings 2-3℃ lower temperature than retail edition, but it causes more noises when the fan runs at maximum speed. Let’s check out together what differences they have. The above one of each group is media edition, and the other one is retail edition .........

Probably if the clocks were different and with additional memory. The GPU and memory will probably perform within 0,1% of each other between "review" and "retail". Maybe the OC is different but it seems like everyone is hitting the 830MHz boundary so that doesn't seem to stop it.Quote:

I know there is no "balance" in this industry or in the minds of people but I personally think someone with both cards should conclusively test one versus the other's power consumption.
If I was one of those reviewers who received the version that won't be available at retail until XFX releases their card, I would be pretty ticked off.
XFX First to Use Premium Reference Design for Radeon HD 4770
http://www.techpowerup.com/92862/XFX...n_HD_4770.htmlQuote:
XFX continues to show enthusiasm with its ATI Radeon line of products, by coming up with the first Radeon HD 4770 accelerator for the market to use the premium reference design for Radeon HD 4770 (model: XFX 4770ST D5 512MB). AMD had come up with two choices of coolers for its partners. Most of them choose the one which is more cost-effective, so the sales margins could be improved in an already tight pricing-segment.
XFX used the premium reference-design cooler and PCB, with a major difference that it comes in black instead of red. XFX has so far had a knack of trying as hard as it can, to color its cards black. The company did so with the Radeon HD 4870 reference design accelerator recently. This card retains the reference clock speeds of 750 MHz (core), and 800 MHz (memory). Given that XFX chose the more expensive parts in making this card, it will pass on the premium to the consumer, making it slightly more expensive than the reference design cards in its league.

Well, after looking at your review and Anandtech's it seems like the power consumption is the same. At idle, it's a bit worse than 4830 (~8W) but at load is better(~18W). Compared to the 9800GT it's about the same too. And I assume by what you wrote and previously written that you have a retail card.Quote:

So maybe it's just you blowing things out of proportion?
I'm not complaining since I got a retail version. What I was saying that that people seem to react differently to ATI's flubs than they do to Nvidia's. It was more a comment about human nature rather than anything else. ;)Quote:

I can only see only two wires powering the fan so i though no PWM = no fan control :confused:Quote:

This development of the lack of some hardware on the board has really turned me off to this card though. ATi, it isn't liked when nVidia does it, what makes you think it won't be minded when YOU do it? As the picture above shows, even the XFX board is missing the same hardware. No thanks.Quote:

I hope your right oohms, cause i just pulled the trigger on two XFX 4770's. Will probably get them end next week.
Regulate the voltage to the fan, and you'll regulate the fan speed. It's perhaps not as "smart" as PWM control, but it should work if the bios/software allows it.Quote:
