Previously , I always used laptops for gaming, and now I'm going to build a low spec PC just to see if everything works out well. Its going to have 8GB RAM. I only want to game on the pc, but i know, i know, the specs are not great, but its a start right? All i need to know is will the Pentium G4560 bottleneck the GT 1030.(or vice versa?) And is a 450W PSU good for this arrangement.
