Wait til tommorrow, as theres likely to be more leaks of info by then.
It is a great time to build, as theyre just around the corner.
As to pricing, no one knows
The info is just now going out to reviewers, so more will be known shortly
"AMD's performance segment will be the new flagship Radeon HD 5870 model for $ 299 were pronounced 'lık contrast to the price information for the Radeon HD 5850 is yet to pronounce any price information, even if there is the Radeon HD 4870 and 4850 models, pricing for the following when considering the RV870 Pro GPU 'water will be powered from the Radeon HD 5850 model at $ 249' lık overseas sales price to have to come up, but sales, especially in terms of number of AMD-ATI's main weapons are expected to be the Radeon HD 5850 model so far for any price, especially pronounced let's not specify. "
Whats interesting is, on other forums people are again discounting the 5xxx series perf, saying that with this pricing, it cant be much.
I'll comment here, that this was the same response when the 4xxx series arrived, but people were just conditioned to nVidia outragious pricing.
Its also the saem, or close as the 3xxx series was, and the rumored perf on the 5xxx series seems to be a bit higher than the 3xxx vs 4xxx jump was
So, its very possible, as ATI was after marketshare last time, which theyve gained, but couldnt quite shake off the G92 series in lower end market slots
This time around, there wont be any, at least until nVidia releases a 40nm G200 alternative, which wont have the cheaper advantages of the G92s, and will make it very hard for nVidia to compete in the overall price perf game
