Can I play ARK Survival Evolved? Consider your setup: i5 4690k, EVGA GTX 560, 8 GB RAM.
Game needs the following specifications: OS must be 64-bit Windows 7 with Service Pack 1, or Windows 8 with a 2 GHz dual-core 64-bit processor. RAM should be at least 4000 MB, and the system needs a DirectX10 compatible GPU with 1 GB of video memory. The graphics driver must support DirectX 10, and the hard drive should have 20,000 MB of available space.
GTX 660 meets the needs as it exceeds the minimum, which is 1GB of VRAM.
You could try using it with the 1GB version of the HD 5450 if you really wanted to.
