Choosing between Pre-built and from scratch gaming pc

[kmang]

Hello, i have a factory pc and have recently decided that i am tired of the mediocre performance, and i want to get a new gaming pc. After going through a bunch of forums, i have compiled this list of parts that suits my budget of around 700 dollars.

On the other hand, i have also customized a pc at cyberpowerpc. It is a tiny bit better and is a bit more but it is prebuilt and has a three year warranty. What do you guys think?

You should be investing less into your CPU and more into your GPU.
Both the builds are good, but your build on PCPartPicker is missing the Power Supply.

But that doesn't matter, because the Corsair CX600 given to you in the Cyberpower PC build isn't good anyway.
Here's what I say we should do.

We downgrade the processor to a 6300, get a good cooler and overclock it real nice.
Then, we invest in a better GPU, which in the end would give better performance.
I keep some of the parts such as the motherboard and case, because they are all personal preference, or are already solid components.

Here's the build revised.

I got different RAM because this one is cheaper, but is still DDR3-1600, so it's still good.
This system misses the Power Supply as did yours though, so you will have to invest a little bit more to get a good quality Supply. Here's a good example.

The ram's speed i had before was DDR3-1866, i am not sure if makes that much of a difference but i think it would be worth an extra ten dollars. Also i think the 270x is pointless as an overclocked 270 outperforms it. Also i have spare thermaltake 600 watt PSU to use.

The question is, does a R9 270 overclocked out perform an overclocked R9 270X?
I don't know, but if you don't see the R9 270X as worth, then just stick with the R9 270 if you can overclock it.

I wouldn't recommend using the Thermaltake 600W PSU to use anyway, Thermaltake is a hit and miss brand, and isn't as reliable as the Power Supply I've given you in the other post.

Plus, I'm not sure if the difference between the DDR3-1866 and 1600 is massive, but it might have a difference in rendering and video editing, if that's what you're into.

All in all do you think i should try to build it myself or get the prebuilt one?

Personally, I would just build it myself.
