      The problem is humans are not good at coping with decissions that involve more than three different factors. So in the end the best is to boil it down to the three things that are most important to you and rate the choices on those items. Or you can just ask for a fast one.

      This is very true. First think about what's really important to you. Is it excessive amounts of raw power? Is it cost? Is it noise? (It was for me.) Is it low power usage? How important is compatibility with future components really? (Most likely you'll just buy a completely new PC again, right?)

      What are you going to use it for? Web + mail? Programming? Some gaming? Heavy, state-of-the-art 3D gaming?

      Most likely, you'll want a healthy balance of these things. People who assemble PCs for a living will probably know what you want, because they've sold the same PC to thousands of others already. If you have unusual wishes (noise is too often ignored IMO), then it's wise to do some research into that specific area.

    Just find a reputable computer seller and order a machine that fits your budget. It'll probably run whatever you need it to run. If Oblivion is the heaviest game you're going to run, you can be done for about $500 probably.

    If you don't want the same boring standard machine that everybody else has, then you'll have to do some research. I did that 2 years ago. My main resource was Silent PC Review because I was tired of my old jet-engine-soundalike. AnandTech is also a good source, as is Tweakers, if you happen to be Dutch. Lots of articles on those sites will refer to Tom's Hardware, which does benchmark graphs, but really, just get what everybody's recommending.

    Two years ago, I went with:

    • Intel Core 2 Duo E8400 (brand new at the time, very fast, very low power usage, therefore little heat) with a passive Scythe Ninja cooler,
    • ATI HD3850 (new, powerful, not overly expensive, good for all games expect Crysis, low power usage when not doing 3D stuff) from Peak (cheaper than other HD3850s because they had a badly fitted cooler which I was going to replace anyway) with passive Accelero S1 cooler (very effective passive cooler, and very cheap).
    • Seasonic S12II-380 power supply (SeaSonic has the quietest PSUs, and 380 W is more than enough for a modern PC that doesn't try to waste as much power as possible),
    • Antec Solo case (Antec makes the quietest cases, but stay away from their power supplies)
    • Some new Samsung harddisk that everybody else was using too.
    • Some Gigabyte motherboard with P35 chipset, which was what you needed two years ago

    All of this cost me about EUR 1000. Very happy with it. Dead quiet, too. Mind you, this is from 2 years ago. There's probably better, cheaper, quieter, faster stuff around now, but I'm not keeping up.

    As for the dual core/quad core stuff: how many heavy CPU-using applications will you be running at the same time? Will your heaviest applications be able to make efficient use of multiple cores? If you don't know, go with dual core. One for the main app, one for everything else. No need to have to extra cores that are only idling all the time.

I don't have a specific example at hand, but I have seen it when using the Intel sspec finder tool on their website.

  17. My Experience by gaelfx · · Score: 4, Interesting

    I recently built my own computer for similar purposes. I needed a box that would download things all day and output via HDMI to my TV, but I placed an extra constraint on my system: Linux compatibility, or at least a reasonable degree of compatibility. So, I researched available parts, using price as the first method of siphoning all the dreck. I live in China, so, for example, the processor's price ranged from a few hundred yuan (about 50 bucks) to about four thousand yuan (closer to $500). I decided not to pay more than 400 yuan for my processor, and right there, I cut out about 90% of the processors I had to research. I decided from then that I wanted a 64-bit processor and I would only look at the top 3 FSB's out of those processors, and I chose Intel because my previous experiences with Linux and AMD procs was somewhat dubious. Everything else kind of fell into place after simply choosing the proc, save for the GPU, which I chose for it's Native HDMI port, high-ish (1GB) dedicated memory and driver support in Linux. So that part was even easier.

    Your situation seems a lot simpler than mine though, since you only have two constraints: Oblivion (don't know what it is) and 1080 video to a TV. Basically, what you need is any computer matching the requirements for playing Oblivion (I would go a little beyond recommended specs for running it) and with a NATIVE HDMI port. If you spend time worrying about complex names for different series of nanometer sized pieces of wire hypersolderized together, you will drown in the hopelessness that is marketing and advertizing and general rhetorical BS. Find out what specs you need to do what you want, if you're using Linux then check for compatibility issues in the forums of the distro you use or plan on using, and what you need to buy should pretty much be spelled out for you in pretty simple choices. If you're using Windows, you have a lot less to worry about since you don't really have control over those sorts of things, just take whatever has an HDMI port and enough RAM and cycles per second to run your game.
