Can someone please post a link to Amazon for parts to build a new PC. I only want parts from Amazon and my budget is 1,300$$$. I don't need Windows or a mouse, keyboard or monitor. I want to have the Gtx 980 in my setup and be able to run The Witcher 3 with 45+ frames with physx enabled. If you can perhaps explain how I can use a weaker/cheaper nvidia card to utilize physx for the witcher 3 that way The 980 can focus on running the game maxed. Please only answer if your linking parts from amazon.
