Crosmando: Is putting it together yourself completely out of the question? You will save a lot of money doing it yourself and it's very easy, modern cases don't even use screws so you don't even need to use a screwdriver, you just slot it in, and the parts themselves come with instructions. The pre-built shops are going to put 20-30% on-top of the cost of the parts themselves put for doing something that takes them less than a hour.

I'd suggest you start here: http://4changboard.wikia.com/wiki/Falcon_Guide
And then buy according to your budget.

KneeTheCap: Th-they don't use screws anymore? H-how can I make it short-circuit anymore then?
(If they got rid of screws, good riddance. Those things were a system killer for me in the past)

Leroux: (...)
Thanks to everyone who's willing to share some advice! :)

Leroux: I can't check at the moment, but from memory it's a duo-core 2.1GHz with 4 GB RAM, 250GB harddisk, and it used to have a GeForce 7300 LE, now it runs with onboard graphics. So pretty low standards. ;)

Psyringe: That's a formidable machine as well. I'm not too fond of ASRock motherboards though (they are one of the cheapest brands on the market, and the ASRock board that I once had never worked really well, but others like them). And I think the PSU needs more power for this hardware. Don't skimp on the PSU, especially not if you're planning on keeping the same machine for many years.

Psyringe: If that's your goal, then you can probably achieve that with a much cheaper machine. An i3 CPU would be sufficient, and you could downgrade the graphics card as well, though I can't tell by how much - I have little experience with cards below the nVidia 560. I _can_ tell that the 560 is already more than enough for what you have in mind, you wouldn't even need a 560 Ti.

What is your current hardware? (So that we can get a grasp of what you're used to.)

I wouldn't go below 8 GB RAM with a 64-bit operating system, but given your target performance, I'd say you could definitely go with a weaker/cheaper machine than the ones you posted.

Edit: If you value longevity higher than peak performance, then you're probably better served by buying high quality brands with lower actual performance. And you should probably tell that at other forums as well where you ask the same question, because you'd then have unusual preferences. Which is absolutely no problem, but people will usually suggest systems targeted for different goals when you ask them about advice.

Edit 2: One other thing that I keep forget mentioning is noise. Modern graphics cards can be pretty loud even if if advertised as "silent". If performance isn't the penultimate goal, then you have the option of getting a low-noise PC; might be worth a consideration. I know that this is important for me since my PC stands right next to a bed in which two people sleep at odd and varying times, but that's probably an unusual scenario as well. ;)

Fenixp: Now that I think of it Leroux - you have managed to wait quite long already, wouldn't you mind lasting another year or so? Just saying, because in a year, next-gen consoles will be out and you will be able to get a PC based on their spects, pretty much ensuring that anything in the following 4 - 5 years will run relatively well. Just don't buy a weaker PC than that mentioned in the OP - saving money now is nice, but it'll get outdated that much faster.

Crosmando: Only if you plan on playing bad console ports for the next 4-5 years.

Fenixp: No, if he plans to play vast majority of videogames which will come out for the next 4-5 years, including, but not only, console ports. I thought you have apologized for all the trolling the other day, guess it doesn't mean much - back to the ignore list you go then.

Crosmando: Ignore list? You run a browser script specifically to block users you don't like on the internet? Kinda brings a new meaning to the word butthurt.

Fenixp: As shocking as that is, you can ignore people without a script :-P (Just by the way. I genuinely thought it was rather nice. Oh well.)

Fenixp: Now that I think of it Leroux - you have managed to wait quite long already, wouldn't you mind lasting another year or so?

Crosmando: I can guarantee you the vast majority of games next 4-5 years will be either multi-platform or MMO's. And the ones that aren't will be indie games which won't need much computing power.

Leroux: So, I'm tending towards just getting the Hyrican PC from the OP, since I don't want to build one myself and ordering a comparable custom-build from hardware stores seems to be more expensive even (more or less the same price as the PC in the OP, but without Windows; so all in all I'd have to pay 100 euros more for more or less the same thing).

Only, I read a comment by a user who bought this PC and it didn't sound so good. They write that they like the PC because it's solidly manufactured and fast and already set up for a quick start, but the only thing they don't like is that there's a process called "interrupts" or something that sometimes pushes the CPU load up to 100%, and that it's annoying when the PC just pauses / stutters / lags one to three times for a moment.

It's the only comment I've found on the net, and I have no clue what this user did, if that's a general problem of this set-up or connected to something else and if it's relevant for anyone else, but then again, I'd hate to spend this much money for a PC that doesn't run smoothly. Is this enough to worry? Could that mean that the mainboard is rubbish? Or should I just ignore it?
