As a general sales associate you should be more worried about which DVD's are better windata or phillips? Is this USB cable better than the other one? Answer: Depends, which one has more gross margin? Is NOD32 *really* that good, or do they only push it because there is 39.00 dollars of gross margin in it?
Anyways, as far as XFX, I have no problem purchasing their brand if it will save me a dollar or 2. Failure rate of graphics cards tends to be ~6% give or take a percentage or two depending on brand and real life RNG. If you sell 100 cards only 6 will be defective, probably half of the people that RMA the cards will have a good experience (we all know basing your opinion of a company on anecdotal evidence you gathered from the internet is faulty at best, I mean, lets be honest, people post on the internet to complain). That means 3 people *might* have a poor experience because you sold them XFX. Of course, 1 or 2 of those people won't even RMA the card, they will just buy a new one because they have more money than time. Either way, you might end up saving each of those people 30-40 USD which they can spend elsewhere.
Don't worry so much about brand, because honestly, it does not matter. The customer will be happy if you put together a computer that runs the games they want to play and saves them money so they feel like they got a good deal. Most people you will end up talking to (even at Microcenter) base their purchasing decisions on the all mighty dollar, not the name plastered on the front of the box. You should do your best to keep your suggestions in line with that one fact.
