Hm... there is no performance difference between DDR1 and 2, but there is a quite big price difference. Considering that a X2 3800+ should get around 2.6, 2.7 GHz while E2140s do maybe 3.0-3.4 GHz, somewhat in that area (might be a bit hard cause I don't have too much money to spend on a decent board, but I recon it could be done), I expect the X2 to be a bit more than twice as fast as my current CPU in my applications and the E2140 to be about thrice as fast. So it all depends on what I can get for my old hardware. I've seen boards like mine that sell for 40-50 ? (they are more popular though) while a decent second hand P965 board can be had for 60-70 ?, I save 10 ? on the CPU, change the cpu cooler with little losses and maybe loose 10 ? on the RAM + later upgrade for less. + I should be able to stick in a quad core later.
Yeah, AMD is cutting prices, but I doubt for the low end, especially not for the S939. There is quite a difference between S939 and AM2 CPUs, eventhough they are essentially the same or the AM2 are better. A $140 6000+ doesn't interest me that much because the price is too high for what I get, even when I OC the thing. AMD should really continue to make S939 CPUs, they won't get anyone who want to switch to a new platform to chose AM2, except for new cheap/energy saving systems that would be built around the AM2 anyway no matter what they do with the S939. But there are quite a few people I think that would upgrade their S939 system, thus giving AMD some cash, if the S939 CPUs would be more attractive, e.g. 65nm, faster, cheaper, lower energy consumption.
