CPU/GPU Performing way below expectations

75 degrees is nothing to be concerned about during a benchmark, but it wouldn't hurt to upgrade your heatsink. Regardless, your CPU wouldn't throttle down at that temperature.
It seems to me the test is telling you that your RAM is slow, and you should focus on that.
Ram is relatively cheap, and you may want to get the fastest that your motherboard supports.

That benchmark tells you nothing expect the parts you have aren't the fastest in the world. If anything dudio is right and your ram is the slowest part of that computer, though the difference in fps from 1333 to 2400 is 4fps at most. It's not something to be worried about.

Those arbitrary benchmarks tell the users nothing since its not real world performance, just some numbers. For all you know, it might be comparing DDR3 to DDR4 (being the best) and that's unfair and doesn't shows any real data.

Something is holding your CPU back. It could be thermals, MS processor performance settings, bios settings, motherboard settings or drivers. Once you sort your CPU out, the RAM score will probably come into line (the two are linked because RAM tests require the CPU to be performing optimally). A new heatsink will allow you to overclock but the stock cooler should be fine at stock clocks.
