I've noticed a trend developing over the last few months, if not longer, of people giving technical PC advice who really shouldn't be. I've seen everything from a user recommending someone pair an Nvidia card with an AMD card for "across the board performance" to seeing someone suggest that a 400w PSU was "more than enough for any SLI setup", and more. Sadly I am not kidding - both of these situations really happened, and recently, too.
Building a PC for the first time can be a daunting enough task for newcomers to the hobby without getting conflicting or straight up incorrect advice from people who aren't that experienced themselves. So please - if you aren't 100% sure of what you're about to suggest and why you are suggesting it, don't guess, just don't say it at all. Someone with more relevant and current experience will be along shortly to answer the question. This applies to PC upgrade questions as well - if you aren't sure or can't back up your suggestions with specific reasons why the user should go in that direction and how your suggestion could benefit them technically, then perhaps you shouldn't be giving the advice at all.
Users who continually give incorrect advice regarding PC builds may be asked to stop participating in these topics altogether.
