The folks at FPSLABS have managed to get a couple of HD 3870 X2 graphics cards working together in CrossfireX (quad-GPU action) despite AMD still in the midst of developing a bug-free CrossfireX driver.
Not limiting themselves to the likes of 3DMark06 (due to its dependancy on CPU power), they also put the setup through its paces in both Call of Juarez and F.E.A.R.
So if you're thinking of going all out with 2x HD 3870 X2s then definitely take a look at the results so you get a better idea of what to expect (allowing for a small loss by premature drivers).
The original launch date for AMD's Radeon HD 3870 X2 was to be January23rd. AMD pushed the launch back to the 28th at the last minute, supposedly because the card did not scale well in several games, including Crysis. Following this logic, AMD is also delaying the official launch of CrossFireX because they have not been able to get the performance up to where they would like. Currently, AMD is saying that CrossFireX will launch in late Q1, meaning most likely sometime in March. The first evaluation version of the CrossFireX-enabling driver was released on Wednesday, the 30th of January, and somehow beyond all expectations, it made its way to us.
