If the ability to run up to three monitors on one regular Radeon HD 5770 card isn't quite enough for you, then the latest offering from PowerColor may be what you have been waiting for. The HD 5770 Eyefinity 5 takes the same formula applied to the HD 5870 Eyefinity 6 card (which was pushed back to release at the end of this month), but cuts the number of mini DisplayPorts down by one, meaning you can hook up five monitors in a number of configurations. The card comes with 1GB of GDDR5 memory on board and the same clock speeds as a stock HD 5770 (850MHz on the core and 1200MHz for the memory).
There is no mention in the press release of the maximum resolution supported for each panel when you have five connected and the HD 5770 GPU may be found lacking if asked to run a game across all of those (which I'm sure we'll find out once someone tries it out). For those who like huge swathes of desktop space, the extra monitor support without the need to step up to the HD 5870 version will be a boon. You can see the possible monitor configurations in the attached image.
No official pricing or availability information was given for the HD 5770 Eyefinity 5. Word from CeBit earlier this month was availability in March for around 200 Euros.
