My first 500$ rig is becoming out dated and i'm moving soon and I can't take my rig with me, I can upgrade it with a better PSU and a EVGA GeForce GTX 960 4GB video card but i can't upgrade the CPU because of the type of socket the motherboard uses, Anyways on point, I want to build a rig that can run doom 4 at 60 fps if possible my limit is 1000$ And I can go higher if you say so.
