Really hope you dont use Nvidia graphic cards in any of the computers you build/recommend ?Here's a scenario that DOES happen... a lot, for professional builders.
Customer A says "I want a pure stable PC, there can be nothing overclocking related involved because -I- know that overclocking kills hardware and nothing you say will convince me otherwise... now advise me in those parameters."
Now, say out loud "AMD doesn't overclock their processors, they sneak you extra clocks because they got in trouble last generation and now sneak you free Mhz!"
Say that out loud and think about how the customer who said the first part is gonna react. Honestly.
Edit: Yanno what, nevermind. This is a waste of breath, there are no fellow pro builders here, or if so, they don't care what business they lose for "guessing" specs. I'm clearly out of place.
