I've wanted to build a gaming PC for a while now, but my dream is finally coming to fruition. My uncle has lent me a bunch of parts from his old computers, and I've been looking for good parts to put in and make it a high-end gaming PC. The parts I am getting or already have include: an ASUS M5A97 LE R2.0 motherboard; an FX-6300 with the stock cooler; 32 GB of DDR3 (not sure of the frequency); an EVGA 600B non-modular PSU; and an old mid-tower case from 2007 with a top-mounted PSU. I'm mainly looking for recommendations on what GPU I should get for playing at max settings 60+ FPS. The two main games I play currently are War Thunder and Arma 3, though I enjoy all flight simulators and also hope to get into Escape from Tarkov. I was thinking about getting a Gigabyte Windforce RTX 2070, and though I realized it would be pretty beefy for such an old CPU I was thinking that since most games don't use too many cores it would be fine. Before anyone says to get a used 1080, I'm looking for something brand new and personally am quite interested in the real time ray tracing feature even if it does tank performance, as I will not usually be using it but would enjoy having it. I would be getting a 1440p monitor, hopefully 120hz but I might cheap out and get a 75hz.
After that way-too-long description of what I'm looking for, any suggestions or ideas?
