Before you buy a new PC, do yourself a favor and visit an Apple Store and check out the new iMacs. The difference between owning a PC and a Mac is..........incredible. After you have used a Mac for a while, you'll wonder how you ever "got by" with a PC; (IMHO)
The big problem is, there are not "that many" Apple Stores; when I lived in Cincinnati, before moving to Indiana, I had an Apple Store about 3 miles from my house; now that I live in western Indiana, I have to drive about 65 miles to Indianapolis to get to one.
They can be a great resource if you own a Mac, (especially if it's less than 3 years old) I was have issues with the display on my "old" iMac (8 yrs old it turned out), and I drug the thing to the Apple Store, waited about 5 minutes for an "appointment" with a "genius"..........and he had the thing running again in less time than I had waited ! ( and it cost me nothing ) I don't know of anyone doing that for "old" PC's !
A word of warning though...........once you see the display on a new 27 inch iMac, you'll have a terribly difficult time settling for anything less !
I bought mine at the Apple Store; if I was doing it again, I would order the thing from Apple, (like I did with the last one) and have it the way I want it from the beginning.
The things come with 4 GB of RAM installed; I bought two 4GB modules of memory, (about $90 if I remember right) and they just "plug right in" to (or in) an access port on the bottom of the machine; (you don't have to open up the machine) as soon as I can "get around" to it, I'm going to remove the two 2GB modules that came with it, and replace them with two more 4GB modules, which will give me a full 16GB of memory. (Then I plan to get a few software things that need lots of RAM)
A few posts back, someone mentioned that there is "essentially no difference between PC and Macs"; I'm not a computer "guru", I'm not a "geek", and I'm definitely NOT an engineer..............but I just happen to be fortunate enough to have a son who IS all of those things. He has been developing weapons for the U.S.N. for about 24 years now, and is the main reason why I bought my first Mac, (a "mirrored door" power Mac, about 12 or 14 yrs ago. ( Having a son with a BS. a MS, and a PhD in EE makes it pretty handy to get the "straight scoop" about computer "stuff" !)
And storage capacity.........it's getting cheaper than potato chips ! My new machine has a 1TB hard drive, and I purchased a 2 TB external HD at Sam's club........(for less than a hundred bucks !) (now if only diesel fuel and gasoline would do that ! )
