Even though it won't be available until later this summer (August), I guess late last night was the time for several sites to publish their "exclusive" previews of the HD 4870 X2. Apparently this card has what it takes to give you FREE (no FPS decrease) AA (up to 12X CFAA) in games like Age of Conan. Wow. This is made possible because of the way that the 4800 series processes anitaliasing:
...Custom Filtering AA (CFAA) is a method employed by the Radeon HD 4800 series to improve antialiasing image quality by using an edge detect algorithm. The beauty of this technology is that uses the stream processors to perform this action and does not tax the framebuffer at all. That means you can get high quality AA (equivalent of 12X and 24X AA) without the cost of using up memory bandwidth and capacity, it uses the shaders. The downside of course is when you are in a shader intensive game you can’t exactly spare the shader horsepower. But, with a setup like Radeon HD 4870 X2 with 4-GPUs powering the game, it has a ton of shader horsepower, 3200 stream processors at your disposal!...

And the black PCB is a nice touch too. I hope they go with that.

The card is the same length as the GTX 280. This pic makes it look really long.

@Mach5Motorsport- Most full tower cases will definately be able to support both of lengths of these cards. I can't say the same about mid tower cases though.

I know zero uber gamers that still use full tower cases. Sure, those people are out there. But come on! Who really needs a full tower case in this day and age?!?
Wasn't it ideal to minimize the case footprint and reduce the space?
(oh, to use a bleeding edge vid card I guess) ;)

Its all good I guess if you have a small tower cause you got small money. I don't have that problem though.

i wonder how the 4870 single would work with 1 gb of ram over 512 mb (same question for the 4850)

seems some games are still CPU limited .
@Naito - What would you call beating nVidia fair and square ? Simply adding a shit ton of stuff onto a single GPU and selling it without a real profit ( or at a uber high price ) and making a half-assed midend card ? In my books ATi beat nVidia fair and square .

P.S. I'm also excited about the Nehalem microarchitecture - native quad/oct cores, hyperthreading, new instruction sets and many more. Can't wait. :D
