Just curious... you think you'll be getting PS5? Because if so, leaks suggest the PS5 gpu will have two modes for PS4 compatibility: one for base PS4, one for PS4 Pro. And the PS4 Pro version of SOTC runs at 60 fps. It's still brilliant at 30 fps though, that's how I played it on my PS4 Slim.
Supposedly we'll be getting the official reveal of PS5 in the next 4 weeks or so. I was going to buy a new gpu until I saw a credible leak claiming PS5 will have the gpu power of a graphics card that costs $400 right now on PC. I would normally write that off but a pretty respected youtube channel seems to think its real from checking with their sources (Digital Foundry -- they're the guys who Microsoft had officially reveal the specs and do performance analysis of the XBox One X before it came out). So now why pay $400 just for a ing gpu if I can pay $500, get that gpu, an SSD, and a pretty killer cpu while also getting access to all the next gen PS5 exclusives. LOL PC gaming it looks like.
