Hehe - I don't think that you have to worry too much. In its current state (with Friday's beta patch, and before today's Steam update) it runs very well on my current (hardly new) system. It's definitely playable with minor graphics tweaking and looks good too, as long as you don't expect it to run brilliantly on max settings.

I freely admit to being a huge fan in its current state, and am currently really enjoying the campaign mode. I think that by your release date a lot more of the current (relatively minor) bugs will be resolved, but then my opinion can hardly be considered unbiased.
