AMD’s Radeon HD 5770 & 5750: DirectX 11 for the Mainstream Crowd

The Test
For the 5700 series launch, AMD issued some new drivers as the previous 8.66 driver set did not include support for these cards. The driver set we used for these cards is 8.66.6, which is from the same branch as the earlier drivers. In our own testing, we haven’t seen any performance differences between these drivers and the previous ones on the 5800 series cards, but AMD did note that certain configurations might see a small performance boost. As such our results are still using the original 8.66 driver for the 4000 and 5800 series.
Also, as AMD sent us a pair of 5770s, we have tested these cards in a Crossfire configuration. This configuration is largely academic, as 2 5770s is just shy of the price of a 5870 and brings with it all of the limitations of multi-GPU scaling as compared to single-GPU scaling.
On a final note, our 5750 sample is a 1GB card.

sorry, if this seems newbest since im still using DVI. anyway, i did a quick peak at apples site and only saw minidp to dvi dongle. however, i jumped over to monoprice and found this:http://www.monoprice.com/products/product.asp?c_id...">http://www.monoprice.com/products/produ...1&p_...
would that work?

Nope this wont work, the card(s) has only two TMDS's for one DVI and one DVI or HDMI, you can't use two DVI's + HDMI...if you want to connect the third monitor you have to use Display Port, and adapters won't work since DP on this card doesn't support DVI single Pass through ( this will need a seperated TMDS chip )
there's some devices that support DVI/HDMI pass throught using DisplayPort, I'm talking about Apple latest Mac's where they dropped DVI/HDMI and replaced it with DP... that one supports DVI/HDMI adapters as it has it's own TMDS chip which is required for DVI/HDMI signals...

Monitors with HDMI seem fairly common and DP-HDMI adapters appear to be cheap. Could you do DP-HDMI, HDMI, and DVI for a triple monitor setup?Ryan Smith - Tuesday, October 13, 2009 - link
DP-HDMI is still a passive converter, so it still won't work.Ryan Smith - Tuesday, October 13, 2009 - link
No, it has to be an active (powered) adapter. You can tell if one is active if it has a USB plug, since that's where they're drawing power from.Minion4Hire - Tuesday, October 13, 2009 - link
It has to be powered if you wish to run dual-link DVI. The single-link MonoPrice adapter will work fine for resolutions up to 1920x1200. But most people looking to run Eyefinity will probably be wanting to go whole-hog with 2560x1600 given the large price tag already associated with such a setup.kzig - Thursday, October 29, 2009 - link
If I want to run 3 1280 x 1024 monitors together as 3840 x 1024 in Eyefinity, will I need an active adapter, or can I use a cheaper passive one?BladeVenom - Tuesday, October 13, 2009 - link
The Apple one is poorly rated. Dell has one, but it to is $100. And just to rerepeat that, it has to be an active adapter. http://accessories.us.dell.com/sna/products/Cables...">http://accessories.us.dell.com/sna/prod...us&l...Ryan Smith - Tuesday, October 13, 2009 - link
I was going to respond to this, but Xajel took the words out of my mouth. Just read his post, it explains why an active adapter is required.bijeshn - Tuesday, October 13, 2009 - link
Phasing out the 4870 is a bad idea. With time I look forward to the 4870 dropping even lower in price...
