This post is a week older now but replying so that someone may find it useful if not the person who started it.Suiseiseki · #4Kind of depends on what your primary use for that computer is going to be. I assume it'll be gaming. With that said, it helps to have a starting budget so you can work within that and choose better parts as you need them, rather than going crazy on the latest gear all around.The major parts you're going to need for your build are:CPU
Your CPU is the chip inside your computer which does the calculations. Your options for manufacturer are limited to AMD and Intel; the Intel i-series (namely the i5 and i7) will likely be your port of call since they can outperform AMD's chips in some areas (but cost more). The higher-end Intel chips are kind of finicky with RAM selection and cost slightly more when it comes to performance:cost ratio. AMD's current chips cater more to higher-mid to low-high tiers of performance requirements. They tend to run quieter and cooler in my experience, and give more bang for your buck if you're on a tight budget.
AMD CPUs cost less but if you have budget go with intel i7 or i5.
AMD CPUs generate more heat, so if going with AMD buy extra cooling fans :P.
Either one you pick just be sure to get the higher CPU within the series like i3 320 is better than i3 310 but a Core2 Quad 3Ghz is better than both (although from lower series).
Look for more cache memory in CPU ex. 7MB L3 cache.
Higher the FSB the better. Look for at least 1667MHz FSB.
Also higher frequency is better. Go with 3.0+ GHz.
Suiseiseki · #4Motherboard
This is a big deal. Generally you'll select your motherboard after you've chosen your CPU, as different CPUs require different sockets (AM3 for AMD chips, Socket 1366+ for Intel. Make sure you check this). USB 3.0 support is being phased in, so if that gives you a hardon by all means get one with it. If you're a massive graphics whore and for some ungodly reason want two graphics cards, make sure your board has at least two PCI-Express sockets and supports CrossfireX or SLI. Four to six RAM slots are standard now as well.
For nVidia:
If you are going for High budget get a SLI-ready Motherboard (If buying 2 Graphic cards) (for 3 cards buy Tri-SLI).
For ATi:
If you are going for High budget get a CrossFireX-ready Motherboard (If buying 2 Graphic cards).
You can go with USB 3.0.
SataIII is also there.
If not buying a Soundcard pick a board with 6 or 8 Channel Audio.
Also take a board with DDR3 ram support.
FSB at least 1333 MHz (1667 MHz preferred )
4-6 RAM slots must be there.
Suiseiseki · #4RAM
Branding? Corsair has reliable RAM modules. What you're going to want is at least 4GB of DDR3, clocked at either 1333MHz or 1667MHz. If your board and CPU support triple-channel RAM, up it to 6GB.
Depending on FSB support of motherboard take RAM. Like for FSB 1667 take 1667 MHz not 1333 MHz (both work but...)
Take at least 2 X 2GBs .
Suiseiseki · #4Hard Disk
Up to you, really. I make do with a single 500GB SATA drive. I'd suggest against a Solid State Drive since you don't seem to be a power user who likes superfast booting; they can be more hassle than they're worth for a newbie. 1TB to 1.5TB should be fine.
Go with at least 1TB SataII with 7200 rpm.
Suiseiseki · #4Graphics Card
This is the fun part. Your two main choices are cards from nVidia or from ATi/AMD. You're going to want to read around for sure on this one. The hardest-hitting card on the market is nVidia's GTX 580, but that carries the downside of having a rather large power draw, being expensive and it can be rather noisy - the GTX480 is the next step down and has a similar set of issues. AMD's top-performing card (once again, from memory) is either the 6870 or the 5870; the reviews have not been clear on which has better performance overall. They are, like much of AMD's gear, aimed more for builders on a budget but are still very powerful cards in their own right.Getting two graphics cards (usually of the same type) will allow you to CrossfireX/SLI on ATi and nVidia cards, respectively. This increases your power draw but can give excellent results in performance increases.
For games GRAPHIC CARDS are MOST important. (not shouting :D).
Go with GeForce GTX cards for high range in nVidia.
2 Cards doesn't mean double performance It gives 1.5 (1.8 in best cases) times performance.
I say go with nVidia GeForce 480 GTX (1 or 2 choose by budget).
Take card which has at least 1 DVI and 1 HDMI (HDCP).
Multi monitor is NOT supported in SLI mode.
SLI / CrossFireX can be configured with two different supported cards like GeForce 260 GTX + 9800 GT or 250 GTS.
It will support DirectX 11, Cuda, OpenGL 4.0, Pixel Shader/Shader Model 4, PhysX, 3D Vision.
Suiseiseki · #4Power Supply
Once all of the above is sussed, find out the maximum draw (in Watts) all your components are going to take. Add another half of that on top to get a power supply with plenty of overhead room that will act on maximum efficiency. That can be kind of impractical when you're reaching a max draw of 600-700W, however, so adding 200W to the total is a less efficient but much easier and cheaper way to do it. There are certain brands you should be using; cheap power supplies can die very quickly and have low efficiency ratings.
GET SLI-READY 1000W+ Power Supply
Corsair or CoolerMaster are good brands to choose.
It will do fine with anything mentioned above ( excluding Tri-SLI 480/580).
Suiseiseki · #4Monitor, Keyboard, Mouse
If you need to replace them, by all means do so. Logitech and Razer both have decent keyboards and mice, but I'd advise against Razer at the moment, their 64-bit drivers are buggy.
A 14" monitor with GTX 580 is useless USELESS !!
If you have at least 22" Full HD LCD/LED monitor then fine else go for LED 22"+ Full HD ( 3D Vision :P).
SOUNDCARD
Buy a good PCI Soundcard with 8 Channel Audio.
Must Have SPDI/F output.
But Without good Speakers it is useless Of course :D.
Gamepad
If you play Racing, Fly Sims, 3rd Person RPG/Shooters, Sports, etc. Buy one Gamepad.
I have 2 XBox 360 Wired controllers and they rock !!
Try Dark Void or Bioshock with one.
It's best controller for PC.
For pure Flying/Racing games JoyStick is better.
ODD
For enjoying HD content you MAY buy a Blue-Ray Drive.
Suiseiseki · #4OS
Should be Win7, and since your budget is high, Win7 64-bit to take advantage of at least 4GB of RAM.
Take Windows 7 x64 (64 bits) Ultimate.
Correct me if I am wrong somewhere, But I am Damn Right. :P
