Since 1.3 & the 60% off, I am thinking of getting NMS. The only problem is that I don't know how well it'll run on my PC:

-Windows 64-bit
-8 GB RAM
-AMD Radeon HD 6570
-8x Intel I7 3770T @ 2.5 GHz

Anyone with similar specs had any issues?

Edit: More specific

Please could you note the model of graphics card?

I have an old AMD HD 6870, it is acceptible (but intermittently choppy) on lowest settings. What is really slowing NMS down on my PC is that the 6870 only has 1 GiB of VRAM where as NMS requires at least 1.5 GiB (will be upgrading to something with 2 or 4 GiB of VRAM soon).

You should be sure with your specs, to comparing them.

I have something like an I7 and an old NVidia - I forgot the type. But it runs well.

Your 'Old Graphics Card' will probably give you problems, depending on what it is.
