What you have here is a very typical gaming build on a tight budget. No bells or whistles, he has simply picked out a lot of components that are very value priced, yet will be powerful enough to run games, and topped it off with an excellent GPU.
Is he lieing? No, not really, no more than just about any advertising you see any place these days. But he is laying the bs on pretty thick.
Is this an impressive build? No.
Is this build worth what he is asking? Maybe to some people, not me.
I especially do not like he does not have access to or stock any parts....he is simply going to take your money, go someplace like newegg and buy everything, put it together in couple of weeks and then ship it off to you. Just another guy out there who thinks they can make a few bucks by building systems for gamers. There are hundreds of these people around, and hundreds more everyday who are thinking about doing the same thing.
Problem is, there is no money in doing this, it is not worth the time or effort, and these people have no real clue what this is going to cost THEM in the long run, and they don't stay around for long. The only way to stay in business doing this is by building true high end systems, where they buyers are willing to pay more to get more, and then you must be able to back what you build. This guy is trying to target people who apparently do not have the money to buy a high end system, and his profit off building these "value" systems is very, very thin for the time and work he has to put into it.
This is exactly the type of builder anyone with common sense would avoid like the plauge. He may have the best intentions in the world, but when your system takes a dump in 3 weeks, his phone number may suddenly be a non-working number.
