Nobody knows?

 

I have been looking into this very question. Seems that the cards are very similar performance and price-wise. They have some differences however:

 

GTX 285 1GB - avoid 2GB version, final cut pro doesn't like it

see http://netkas.org/?p=105

- slight edge in benchmarks

- have been reports of these burning out, EVGA gives full guarantee which may be something to consider

- has CUDA for using GPU for processing (very few apps use this but is considered by some to be better than OpenCL)

- problems with dual display (not sure if solved yet)

- Has SLI, but no support in OS X (yet)

 

Radeon 4890 1GB - dual dvi edition (make sure not to get DVI/HDMI edition)

http://netkas.org/?p=212

- both displays work with appropriate driver

- some people have had problems with fans running full speed

- easier to install?

- some say better quality components

- runs cooler

- crossfire support but no benefit in OS X (yet)

 

If anyone has updated information or notices inaccuracies, please let me know.

I haven't got either card yet.... so advice appreciated

 

There is no compatibility list that I found yet, may be a good place to start it.... so far I have been able to glean the following, please post here and we can update the list.

 

Radeon 4890 models

sapphire ?no 60Hz displays

asus?

msi - fan running at full speed bu dual display ok

xfx - fan problem

HIS - fan problem

Club3D Radeon HD 4890 -fan ok

Powercolor 1GB, model AX4890 1GBD5-UH OK

ATI fanboy? B)

 

- both displays work with appropriate driver - ok

- some people have had problems with fans running full speed

- easier to install? - both use PCI express so no

- some say better quality components - nobody knows, very doubtful for cards in this price reagon

- runs cooler - Nope, GTX 285 downclocks for an idle temperature of around 40 degrees celsius, 4890 idles at around 58-60

- crossfire support but no benefit in OS X (yet) - No idea.

 

If you want a faster performing card get the GTX 285, want to look more after your budget get the 4890.
