I honestly have to go with PC in this case.
Not that I don't like macs, but they are not suited for all my needs. I have a 21 Inch iMac(don't know the specs really), and it is fine for general computing. I got it thinking that it would be a great thing for me to get into if I was getting into artsy stuff and creativity, which it was-for a little bit.
I then discovered that anything to go beyond basic programs for creativity on a mac is a lot of money. A LOT of money. So I kinda let the creativity go because of price. I then got more into electronics and computers(and of course, gaming), and decided I needed to upgrade from an old dell inspiron 1520. Ugliest thing ever.
So instead of going for mac, I built my own computer, something you can only do on a mac if you have a few thousand dollars you aren't doing anything with. I spent plenty of money on my machine, but much less than a mac and much more connected to the hardware than a mac.
Side note: The specs are an amd FX 8150 I think, 8 cores, 4.1 GHZ each ATM.
32 GB DDR3 Ram with a rather high cycling speed and frequency. Geil EVO I believe.
an EVGA GeForce GTX 680 FTW Standard, 4GB 256-bit GDDR5. Amazing thing.
An asus M5A97 Motherboard,
a CORSAIR HX Series HX850 850W ATX12V Power supply,
and a 480 GB
Corsair Force Series GT 2.5" 480GB SATA III Internal SSD, along with a 2 TB HDD for other stuff. Operating system of windows 7 Ultimate 64-Bit on the SSD.
Anyway...... Those specs are, to my understanding, not reachable on a mac unless you buy a high end mac pro, which would be better than this. one cannot compare to twin i7 hex cores, but that is a entirely different ballgame. And that sort of machine is an insane amount of money for the stuff inside of it. I find that the interface with windows can be a little trickier, but I want to know about my computer's guts. I wan't to know what it is doing and why it is doing what it is doing. I honestly like to work the kinks out myself. I find I have much more control on a windows than I do on a mac. If I feel like browsing the internet, sure, I'll use the mac. If I need to do something with photos, I used to use mac but I got adobe Creative Suite. Far better than built in mac stuff in my opinion, and I get a student discount on it.
I am not a huge fan of macs, but I don't hate them. What I do dislike is people who think they are special because they have a computer that they don't understand. When people say that macs are more powerful than PCs, they should see computers that are custom built by the people who use them. If you wan't to just have your computer work and not ask why, go ahead and sink a ton of money into a mac. But if you want to learn about them, build your own. Not every computer that is self-built is that powerful, by the way. My buddy built one that was very nice, as good as a 2500$ mac would be but for about 600 bucks. And if you tell me about resale value and the life of it, I will tell you that a person who builds their own computer Isn't going to sell it. They are going to continue upgrading it, as am I. I will never get an entirely new machine with all new parts. I will slowly remove old parts and add new ones as technology gets better, and eventually my machine will be different than it was a long time ago.
If you talk about how long they will last, a self built computer that is maintained and upgraded on a semi-frequent basis will last forever. There is not really anything that can go wrong with it after time, because to people who build their own, a piece of broken hardware (which is rare), is just a sign that that part needed to be upgraded.
What I'm saying is, if you want to just blindly follow an expensive machine to do your work for you and to not understand how it works, go ahead and get a mac. If you wan't to know your computer and have a powerful one, stop thinking mac. If you want a powerful computer, go with a self built windows. Odds are that if you want a high power computer, you are willing to go through some effort. Mac takes that effort away and replaces it with money, and they aren't actually that powerful. Sorry for the really long response.
