-How much would a good computer for this kind of thing cost?Where would I get it?
-In addition to the computer itself, what do I need to get along with it?
-How often do I need to update/upgrade the thing?What kind of mantinence does it take?
-How does steam work? Ive heard good/bad about it.
-lol,what els do I need to know?Is it realy as complicated as I think it is, or am I just used to computers being crappy because of mine, and theres not as much to them?
1. It really depends on what you want, and how much you need to get. Do you already have a monitor, keyboard/mouse or a way to get Windows 7? If no, then you'll probably need $150-$200 for a monitor, $30 for a keyboard+mouse, and $100 for Windows 7. If you have all of those, then you should ask yourself what you want your budget to be. Do you just want to get a PC on the cheap that can play games like Skyrim smoothly but at low settings, and not really have much future-proofing? Or do you want to be able to max skyrim out in high resolutions?
On a really tight budget (without stuff like a monitor, etc) you could easily get a PC that costs $400-$500 and will play Skyrim very well. Perhaps not on max settings, but well enough to be visually appealing and enjoyable. If you want to max Skyrim out, you could easily make one in the $600-$700 range. This will also run any other game you throw at it for quite a while. You don't really need to go further than that unless you really want to blow a lot of money on the latest and greatest hardware. A brand new $600-$700 computer will remain current for several years, with the only thing you'll maybe want to upgrade between now and then would be a more up to date video card (though if you get a half-decent one now it'll last a lot longer).
2. Other than Windows 7 64bit (if you don't already have it), a monitor, keyboard+mouse, etc then nothing. If you have a DVD drive, etc from your old computer you can totally just use them in your new one so you don't have to buy another

3. They take almost zero maintenance. You might want to clean dust out of it every now and then, especailly if you get spotty performance and you notice a program like HWMonitor stating that your temps are a little hot. How often you upgrade depends entirely on what you get to start with, how spend-happy you are, and how much you want from you computer. If you're felixble with your performance and don't mind running games several years down the line on slightly lower settings, you probably won't have to upgrade in 5 or so years before something becomes really outdated. And if you need to upgrade, it's usually very easy for the most important stuff - just need to swap out the CPU or the GPU instead of getting a whole new computer. This only time this doesn't apply is if you are just simply running on a really outdated processor type, in which case you wouldn't be able to really upgrade as a newer processor type would require a newer motherboard. In which case you'd swap out your motherboard too. This isn't a huge deal to do, and motherboard swaps are very infrequent upgrades. I'm still running off a QX6850 processor from 4-5 years ago and I can still max games out (granted it was top of the line when it was released, but hey - I won it for free!

). If I wanted to upgrade to a newer processor though within the next few years I'd have to get a new motherboard, since the QX6850 uses an outdated chipset.
4. Steam is one of the best things to happen to PC gaming in a long time. The only people who are annoyed by it being required to play games like Skyrim and Deus Ex, are the type that have never used it before and just don't want to deal with such a change. Steam is owned by Valve Corporation, who are the creators of the Half-Life game franchise, one of the leading companies on supporting pro-PC games development, they heavily supporting indie games, and digital distribution (in 10 or so years, almost EVEYRTHING will be digital distribution based). Digital Distribution basically means you pay for a game, then download it straight to your computer. That's what Steam (mostly) does - it's a platform for Digital Distribution. Why this is so good other than the fact that it means all your games and your steam community friends (aka the social aspects of Steam) are all centralized onto one place. It's also great because Digitial Distribution has two huges lead over traditional purchasing of games. You can preload almost all games before release date, so the moment it hits midnight on release you can play. It's also great because PC games are INSANELY cheap thanks to Steam. They are the only people who actually have a person hired for them, who design and prototype experiemnetal sales. For example, this past xmas Skyrim went on sale for 33% off on Steam, a game that was just barely over a month old. They sale giant catalogs of games during these sales (i.e. like getting every THQ game ever released for $70), they freuqnetly have insane deals such as buying Batman Arkham Asylum for $2.50, they do stuff like "Free Weekends" where you can play thier promotional game for free on a weekend, etc. Games on PC are insanely affordable and cheap thanks to Steam.
5. It's really not that complicated! PC gaming is great because in the long run it's much cheaper than console gaming. No expensive periphrials, you can pretty much click a button and instant-have any game of your choice, games are insanely cheap through Steam, PC's can be used for anything (not just games), etc.
The hardest part about getting a PC is figuring out what all the things do in your PC so you know how to buy smart. Upgrading your memory, installing a video card, install a CPU are all LITERALLY "plug it in, you're good to go". I kid you not, it's harder to build a dining table from Ikea than it is to build a PC. The only time you'll ever need a screwdriver is when you install a motherboard into your case.
Here's an EXCELLENT resource that goes over everything about PC building, what the parts do, and every page has animations to show how it goes in:

As for prebuilts? I would avoid. I STRONGLY suggest building your own PC. It isn't that hard, and there's only 1 or 2 things you have to take precations for. The problem with prebuilts are that they are massively overpriced, it's impossible to find a good one from a local store that is worth your time for video gaming (and online ones cost extremely high shipping costs), and often they add a bunch of [censored] to your computer that either slows it down, or does nothing. Such as, many pre-built computers will come with 16GB of RAM (a MASSIVE waste, you don't need more than 4GB on the standard end, 8GB on the "serious workhorse" end) and then totally skimp on the video card (the most important part for video games) because "16GB of RAM" sells better than "XXXX Video Card" despite being labeled as a gaming PC.
Anyways, hope that helped give insight into PC's
