I think the TS has enough info to make an informed decision.
well, your still over paying. At 350, that is about 200 an hour in labour assuming they never assembled a computer before. for a professional, your putting out more or less 466 an hour just for labour. The warranty is not worth that, as most of the parts have an equal or better warranty themselves. At most you should be putting out about 100 in labour. Thats about 175 an hour.
no you don't need one, but it will allow you to overclock and thus extend the life of your computer. But your just as well off with a plain old 2600, which you probably don't need. You probably only need a 2500(k) as it is not hyper threaded and performs about on par for $60 less. That board would be fine.
If your asking questions here, about what motherboard, what power supply, what's GPU, etc, and they have spent a "considerable amount of time" with you, then you haven't asked them the right questions and they haven't offered up any answers or comparisoms or info to you for you to have a basis on what your getting, as this forum has. All they've said is 'here's what you need' and when you mentioned warranty, they of course informed you of that money maker for them. We have members here that have been IT techs for decades, stay on top of technology, and can tell you about every little part that makes up every component-whether its brand X or brand Y. Don't get me wrong, I understand why you want the warranty. If peace of mind cost $125+ per year I'd be in bliss the rest of my life
