A few weeks ago I went to play GTA V, but found that I could not play the game at all. After uninstalling and reinstalling multiple times, verifying integrity of files, and updating all my drivers, with no change at all, I concluded that a pc component must have been failing. I also tried other games, with a similar sharp drop in performance. My PC was 4-5ish years old at this point with 16gb ram and a gtx 1080 graphics card. First I upgraded my ram to 32gb, and that had no change. I then went and got a 3070 TI graphics card from best buy. Last night I installed that, and did a deep clean checking all connections in my pc, but upon testing GTA still runs in an unplayable condition, as do many of my other games. I ran a test pc bench mark, but the results were inconclusive as while it could detect I had a 3070 TI, it couldn't determine model, and would not accept the model number I tried to manually input. If it matters my CPU is i7-6700K 4 GHz Quad-Core. What can I do to troubleshoot further?
