Nvidia doesnt has to worry about a thing.Their top end hardware like GTX 280 still performing really well, 30% more powerful than 4870 and 30% short on 5870.So Nvidia is now evenly balance in the middle and their drivers are far more superior than crappy ATI once.ATI 5870 is one chip design of 4870x2 and they still couldn't beat GTX 295 in most gameS..............so pity.

Did they forget about the past?
ATI took whole 2 years and 3 generation to catch up with 8800 series and beacasue of console porting those hardware still performing really well ,so nobody have worrying about upgrading thier hardware until next generation comes.Then again ATI totally false here.

If ATI so confident about thier new 5800 series,why do they did such 30 sidles comparison to paper dragon ? Why don't AMD do their childish 30 sidles thing with intel and their cpus ?

AMD should watch what they're saying; this could come back to bite them in the ass if Fermi blows the 5870/5890 out of the water.

They presented Fermi at a tech conference planned months in advance. If they didn't present anything, that would've been cause for concern, so they were basically compelled to show what they were willing to in advance of launch. They also didn't make any direct comparisons to the competition, probably because they believe Fermi has no competition.

This is very different of course to what AMD is doing in this case, as they're basically shadow boxing with unreleased parts when they already have their hardware in the channel. There should be no need for this kind of underhanded marketing, the fact they are resorting to this kind of tactic just shows they're scared, and from what we've seen about Fermi, that concern is probably justified!
