I think the minimum specs needs another look over. A 580 or a 5770? The 580 is far, far stronger than the 5770 lol And the 580 is close, if only slightly slower than the 670. Seems like you used the numpad and hit the '8' instead of the '5' to be the GTX 550?
The A8 3870 is an odd chip to pull out as the recommended, i didnt think many people used those. It would have been better to say a phenom II 940/945 or higher, unless its looking for instructions that were introduced with llano that the original Phenom ii's didnt have? Also a 580 or a 5770? Is that a typo or some terrible optimization?
Apparently, that particular i7 isn't a whole lot better than that particular A8.
But, considering that an i7-920 is a Bloomfield (i.e. 1st-generation) core i7 processor, first being released back in 2008, I would say the main takeaway from this is that the game is not CPU-dependent, so that players will want to focus more on their GPUs to play it well.
I'm curious why they specify Windows 7 as opposed to "64-bit Windows." Is this the reason I need to roll-back from 8.1 to 7? I can't put into words how much I hate the divide between app and programs, not to mention the "metro" UI.
