Blopagol: I think those are minimum.
I think in order to play it on high/very high settings, you need a more powerful machine than that. After all, for what I have seen, it will be a very graphic intense modern AAA title, plus all the AI, physics and other aspects of the engine, I expect it to demand a powerful machine.
But on the other hand, I believe in the developers anyways, in that the will try not to make it a system hog as much as possible, and make it very scalable also.
I'd love to the play the Witcher 2, but it looks like the minimum reqs for the processor speed is a 2.2 ghz dual core.
I bought an Alienware M11x last April. My processor is an overclocked 1.7 ghx core 2 duo. Should I even attempt to run Witcher 2 on it? I'm not really looking to spend $45 on something that won't work either...
