I apologize for being rude, and I'm terribly sorry to hear about your friend. I guess you could have just said "reasons" why you weren't going through them anymore.
I totally mis-read the situation. I took it personally, as a system-builder myself, like when a friend of a friend went to BestBuy, instead of coming to me, or one of our other mutual friends that's a system-builder. They bought a PC for Gaming, but they ended up with some i7 PC, but using Haswell Integrated Graphics to play their Blizzard games. I guess it was workable, but I wanted to even GIVE them a dGPU for free, to show them what they were missing, by sticking with the iGPU.
I guess, I didn't want you to make a similar mistake.
Again, I apologize.
Edit: The only reason that I could see, from re-reading the OP, was that you were choosing to buy a pre-built, rather than go through an apparently-trusted PC builder, was that you had "more money", which is never a good reason to buy a pre-built, as even with "more money", you can get a better deal and a better PC through a system builder. Which, as a system builder, I took offense, and thought that you intended to waste money on a pre-built, just because you could. Certainly, upon re-reading your OP, and not knowing about your friend's condition, you can see how I came to that conclusion, and why I reacted the way that I did.
