One quick note: If I were you, I wouldn't ask about whether or not something I bought was a good deal after the purchase. Why? If the answer is, "Yes, you made a great purchase" then I would feel good for about two seconds, then move on. If the answer isn't so favorable, then I'd regret making that purchase (and it's too late to do anything.)
You still haven't posted what you intend to do with that machine, so nobody can say for certain if it was a bad deal. Since you bought a prebuilt system, it's highly unlikely you wanted to invest the time to build a system, so that's out of the picture. Stacking that system up against other prebuilt computers, though (by that I mean the likes of Dell, HP, Lenovo, Acer, etc.) I think that for the price, it isn't the worst deal, but neither is it the best deal.
Assuming you're just an average computer user, that computer is way overkill. In that case, you won't notice anything wrong from using that computer, so why come back to this forum and see your computer getting ripped on by everyone here?
Now, if you try to run any recent game... that's a bit of a different story. Remember, most people on THG select each component carefully then build their own PCs, then overclock and tweak them. They also dislike many stores, such as the one from where you bought your computer. They would never dream of buying a prebuilt computer from Best Buy for themselves. So, I think you should just use your computer. If you do not find anything lacking, then I think you should not care what anyone here says.
But do yourself a favor, and uninstall all the crapware.
