Re: The right price for the GTX200 family...
When the 4870 reviews came out, I made it a point to check performance at 2560x1600 with 4x AA. At three different web sites (AnandTech, HotHardware, and The TechReport), the overall performance of the GeForce GTX 280 was 20% higher than the 4870, but there were only a couple of cases where the difference would have actually made an impact during gameplay. There was no doubt that NVIDIA would need to lower the price of the 280 in order to sell them.
However, I don’t believe that those reviews include results with transparency antialiasing (vs. adaptive AA) enabled, which begins to stress graphics cards that only have 512MB of memory. With these settings, there are cases where the average frame rate in games like Dark Messiah and Oblivion will drop into the single digits on 512MB graphics card. With all these variables, it becomes difficult to determine what the price of the GeForce GTX 280 “should be”, but I’m glad to see them dropping!
