@kbyte-928997 it would also be prudent to browse
the buildapc subreddit. Not only can you find helpful advice, you can also find out information you might not easily get elsewhere. For example,
this post here suggests that a lot of GTX 970s suffer from
coil whine. There's a lot of stuff people don't normally think about too, such as your RAM being too large for your heatsink. Also I recommend against trusting
Newegg or Amazon reviews. Anyone building a computer should do very thorough research. I personally recommend doing a google search for a particular part you're interested in. For some parts you can find something like
an owner's club where you can check out what kind of experience people are having with a particular part.
Naturally you're going to run into a lot of anecdotes on the internet and not everyone's input will be helpful, this even applies for trusted review sites. But it could also save you a lot of grief if you know what to expect.
