Okay first of all, if you are too lazy to learn and just want to buy, plug and play then get a pre-built. As of my knowledge most pre-builts that costs 1000$ have 4060 or 4060 ti, it will be a beast in 1080p 144/165hz gaming.

If you want to build it yourself and squeeze as much performance for dollar, you must consider some things so read carefully.

But before that I've typed these assuming you have basic knowledge, like what is a cpu, gpu, ram, psu, etc...

1-: Desired resolution: you gotta pick either 1080p/1440p(2k)/2160p(4k), the higher the resolution of your monitor the more the cost will increase, alternatively you can rely on the used market if you want higher resolution for lower money, something like a used rx 6800 XT will perform very well in 1440p for low price if you can find it used.

2-: Usage: simple as that, 90% of the time gaming? Get AMD cpu and AMD gpu, mostly gaming but some live streams and video recording? AMD cpu with nvidia gpu, mostly workstation stuff get intel cpu and nvidia gpu.

3-: used parts?: this is up to you, if you're getting used parts you will get more fps per dollar, but at the cost of significantly lower life span for parts and other problems.

4-: budget: should've been the first thing to consider but nvm, if you are going to play at 1080p high settings/1440p low to mid 900-1100$, 1440p mid-high/4k low settings 1400-1700$, 4k mid-high settings 2200$+. These prices should give you the most common fps at about 144 to 165 with graphics settings listed next to them as well resolution. Keep in mind it strongly depends on the game, like you can play valorant at 4k with 1000$ and get smooth fps, but not resident evil 4 remake at 4k.

5- plan to upgrade?: I will not be biased for a specific platform here, but if you plan to upgrade and get the build immediately then amd is the way to go, if you can wait a little bit for intel 15th gen to release then you will have the pick between the 2 platforms, depending on the usage i mentioned before.

6- premium stuff: think of it android vs ios(apple), android phones gives you very strong specs for less than apple most of the time, while apple gives you more applications and unique features with its phones than androids, the same applies to nvidia vs amd graphics cards, want as much performance as possible? Get amd, sacrifice a little performance for more features like premium upscaling, frame generation, lower input time? Get nvidia, I'd STRONGLY recommend researching these stuff and see how much effect the do, like how much nvidia reflex lowers response time and see if it is worth it yourself, or see how much dlss affects the gameplay vs fsr in terms of fps and visual quality.

7-: that's it you're done: considered all the before? Great you're one away from finishing the build, watch YouTube videos on pc assembly and builds, learn some basic things like: ssd types, ram types, clocks and frequency, how to set up and orientate a cpu air/aio cooler. And that's it.

Trust me, it is not boring tho.
