Heyo good day,
This is the advice from Paradox Plaza:
Operating System: Microsoft Windows XP/Vista/7/8/8.1 (64-bit), Processor: Intel Core 2 Duo, 3.0GHz / AMD Athlon 64 X2 6400+, 3.2GHz, RAM: 4GB, Graphics Card: nVIDIA GeForce GTX 260, 512 MB / ATI Radeon HD 5670 (Does not support Intel Integrated Graphics Card), 512 MB, Hard Drive: 4 GB
Operating System: Microsoft Windows 7/8/8.1 (64-bit) Processor: Intel Core i5-3470, 3.20GHz / AMD FX-6300, 3.5Ghz, RAM: 6GB, Graphics Card: nVIDIA GeForce GTX 660 (Does not support Intel Integrated Graphics Card), 2 GB / AMD Radeon HD 7870, 2 GB, Hard Drive: 4 GB
I play with an i5-4570 core and a radeon r9 270x .. it’s like 10% better as the recommended advice.
But, such a computer is expensive … it cost me around 1400 euro = 1500 USD
But, think about buying such a computer..
