The 4870 will premiere in Europe for around 260 Euros from the differences I can see in the 4850 prices.

Therefore, two of them should end up cheaper than a GTX 280. Though that is good news in some ways, people who have SLI mobos will stick with a one card solution and may go for 2x GTX 280 or 260 which is power that ATI will not be able to match until the 4870X2 (aka R700) arrives.
