Living with a Core i3-10105
This processor sits in the lower part of the range and will be the limiting component in most modern pairings. Frame rates will be capped by the chip well before the graphics card runs out of capacity, and no graphics upgrade will change that.
If frame rates are the problem, this is where the money goes. Raising the resolution will not help here in the way it does for a graphics-limited system.
A small cache holds this chip back
6 MB of L3 is modest by current standards, and it costs this chip more in games than its clock speed suggests. Game engines walk large, scattered data structures, so a small cache means more trips to main memory and more stalls on the render thread. Memory speed and timings matter unusually much on a part like this.
