Processor scaling comparisons about 3.5 years ago showed that it took at least an i5-7400 or so to saturate a GTX1060....; ergo, naturally an 11 year old CPU will hold back performance with pretty much any GPU above an GT730, likely limiting frame rates to 50% or less of those possible, and, particularly minimums FPS. (This will vary greatly depending on the game, but, if you were happy with frame rates achieved at lower res, you should at least be able to get those same frame rates now at 1080P, but at high detail/quality settings)
