Man I dunno where u get ur Intel from but it is F'd up big time. 4870X2 better than GTX280, come on, u must be outta ur mind or lost ur marbles.
With 1.4 billion transistors on a single die, GTX280 is the biggest and meanest bada$$ in the GPU community today. Sure HD4870X2 beats GTX 280 but it takes 2 of the Reds to gang up and beat down onw single GTX280. The default single chip HD4870 was never aimed at competing with GTX280, it was lucky enough to match GTX260 in most of the benchmarking tests. What if Nvidia rolls out GTX280X2 or GTX260X2 tomorrow, what do you think is gonna happen to HD4*** series?
This time where Nvidia went wrong was their pricing. ATi cards were cheaper and here we always go for "Sasta", whether it may or may not be "Sunder" and "Tikaoo", just like XBOX360. HD4850 is nothing more than a highly OCed 8800GT and the fact that latter card came almost a year before, HD4850 had time to incorporate DX10.1 and SM 4.0 in it.
This is was just general rambling, lets talk figures now.
The GTX200 series GPUs have 1.4billion transistors on a single die making them even more faster and better than your average dual Core processors.
GTX280 has:
- Peak pixel fillrate-19.3 billion pixels per second!
- Peak texels fillrate-48.2 billion texels per second.
- Bandwidth-141.7GBps (VRAM is GDDR3)
- SP count-240
- Texture Units-80
- Raster Operators-32
ATi may have jumped on to GDDR5 bandwagon to show how advanced they are but to consider GDDR5 as the best thing ever to happen to a GPU is pure n00bish. A friend of mine, who was employed in RAMDAC and also had chance to work on PS3's RAM made it clear that next VRAM generation isn't going to belong to GDDR3 or GDDR5, it belongs to XDR who's production cost is just 20cents a unit right now.
Look I ain't here to teach or preach so just grab the copies of August and September issues of Digit to know more about memory and GPU architectures. As for comparing these cards is concerned, why don't you leave it to Pros and see what they Say about it.

- HD4850
If you are still unable to understand what those reviews say, Use Google Translate!
Even if that also fails well then, Lord save you Boy!
BTW guys look at my GPUz screenshot and look at it very carefully. I think something's wrong with it, I mean the software, as my card is working just fine.
