Bottlenecking websites are full of Garbage. Mainly because Bottlenecks are situational as they can be eliminated by with adjusting the settings, or using a monitor with a higher screen resolution. Also, PC games all use the CPU differently. These sites are making a generalized guess based on the age and core count of a given processor. It's best to look up benchmarks and youtube videos that will show you real world benchmarks.
Many people are looking for a number which gives a generalized benchmark score of a CPU or Graphics card in order to measure it's power, but these scores are unreliable because CPU's and Graphics cards behave differently in different situations. These bottleneck sites take one score and divide it by another to give you what appears to be a legitimate result.
Right now, you can't even get a Graphics card unless it is an older card that has 4gb of VRAM or less on the 2nd Hand market. Even then it's overpriced. There's a GPU shortage going on at the moment that's brought on by a variety of different factors. It sucks, I know, but this has become a common occurrence over these last 3 years due to the rise in PC Gaming and Cryptocurrency mining with Graphics cards. The current shortage is brought on by the listed factors combined with more people working from home due to Covid, materials shortages, an unsuccessful jump to a new GPU manufacturing process, and shipping delays due to less flights.

you need two different website -- the first, search for 'bottlenecking' -- what you want to do is put in your cpu and a junk gpu, then let the site tell you how much gpu it can handle. second, you need a power supply sizing website. internet search will find both. after you have this, go to a gamers webiste like tomshardware or guru3d and check where your target gpu falls in the power rankings and what other gpus are nearby. armed with that, you can go shopping and know the approximate performance/cost tradeoff. then go back to the bottlenecking site ... you probably don't want to spend more for gpu power above about 10 to 15 percent 'more than' recommended for your cpu. have fun -- this'll easily take 45 minutes but it's a good 45 minutes of enjoyment. -- grampa [i built my own, several times]
