The game has changed a little since the bench mark test has been released.
I'd say your looking for something with at least 8g of ram Intel i5 or higher, amd a8 or higher... And for the graphics card something higher than 7640ati or the equivalent of that.
As always the higher the graphic card the better the game will run in theory. Just be careful of software incompatibility if you're building it yourself.
