So, decided to build your own machine, eh?
I built mine too. I was pulling my hair out since I couldn?t play the latest games; either they wouldn?t even install, laughing at my 400 MHz Pentium II, or would crawl at 15 frames per second, all the eye-candy turned off.
Building a new machine is a matter of "How much money do you have?" instead of "What do you want to do in it?" because you said you wanted to play some modern games. Once games are thrown into the equation, you can spend up to US$15.000 (YES, FITEEN GRAND) to build a top-notch rig. Be prepared to sell your car. Dont worry, since 1300 will get you going.
Well, you said World of Warcraft, so you MUST include some decent graphics card. Ati Radeon or Nvidia Geforce will do the trick. I don?t know prices, but think Nvidia Geforce 6xxx or Ati Radeon 9xxx and up. Below these models, you don?t get enough bang, and above, you need lots of buck. The sweet spot is up to you. We are talking about a new PC, so it will have PCI express; some AGP card from previous generations can do equally fine, but your new Motherboard probably wont have AGP.
Well, since it came to mind, motherboard. Again, price and features go in opposite direction, but even low-end mobos will work, because they use the same chipsets as top-notch motherboards, they just dont pack many extra features, like an extra Hard-drive controller, and SLI support. But, they run PCMark just as fast as their big brothers. Check www.tomshardware.com for some fair comparisons.
What you will want:
-SATA support. New Serial Ata hard drives cost as much as their PATA counterparts, pack as many GB as them, work as fast as them, but they make air circulation so much easier, it is not even an issue. You can always upgrage your HD later, but a motherboard is harder to upgrade.
What you might want:
-RAID support. Again, HD feature. If you plan to purchase two identical HDs, and speed up things up to 50%, you will want RAID 0 (stripping). It makes a 20 MB chunk of data, (for example) to be written in 2 hard-drives instead of one, 10 MB in each. So, it is faster, no matter what. Failure of one HD will get you in trouble, be sure. Only if you got enough cash.
Most mobos come nowadays with sound, network, and unlike previous generations, they have specialized chips embedded for each task, instead of forcing your CPU to do everything. In short, any modern mobo will get you going, either for AMD or Intel CPUs. Go for ASUS, ABIT, Intel and avoid "generic" brands. Some extra cash for knows brands pay up.
CPU. Again, price x power. Intel is famous for stability in server functions, AMD is famous for cheap speed. If you plan to leave your machine permanently turned on, go with Intel. You plan to get some extra speed, and not spending much, go AMD. It doesn?t mean roles can?t be reversed, since you may find some 3.4 GHz Intel for a bargain, or get an extra-stable AMD that will run for days, without a hitch. Some 2+GHz AMD or 3+ GHz Intel will get you happy. It is a matter of personal choice, really. Remember to cool them down, and you?ll have no problems.
Cooler and case. you need to worry only if you got some cheap (below $50) case with no extra fans. I got myself an extra ventilated Thermaltake case, and found out that stock Intel cooler would work fine, thanks to the case. Not to mention the extra room, that makes your job, as an assembler, much easier. You can remove any component, without interference on any other. New HD? No problem, it can be installing without removing the graphics card, (as my previous case). Think about it. If you dont have the cash, go for the cramped cases, it is your patience, not mine, that will be depleted after 5 minutes trying to remove a CD-ROM.
Memory. Not much here. Go Kingston, Corsair, and that?s it. Match the frequency supported on your mobo, and there you go. Go 1 gigabyte, at least. Watch out for DDR, dual-channel, ECC (error correction if you want stability, that is) New games are thankful for extra memory. So will XP, Vista, Linux... Remember that if your Graphics card doesn?t have enough memory, it will start eating up system memory. Spend some extra bucks here. It is a gaming rig, after all.
PSU. Power supply. Don?t neglect it, ever. Go 480+ Watts. Dont stop, dont think, go for it. This component, if neglected, can compromise EVERYTHING ELSE. Your graphic card probably will want some extra juice plugged directly into it, your PC will crash if voltages skew out. The power grid around my city is a mess, and my PSU saved my PC more than once. One microwave oven, one VCR, lost to power hiccups. Plus, some of PSUs can help to reduce temperature inside case, since they usually blow the hot air out. Consider also SATA power plugs, extra molex connectors, noise control. Dont go for less than 400W if you think you want 2 graphics cards. Go for brands, also. Thermaltake did great for me.
CD/DVD. Optical drives. You want a CD recorder, and a independent DVD player. DVD recorder is a must if you want to get rid of old VHS, otherwise it is a waste of cash. The DVD will get the dirty job, to read all of those scratchy, dusty, bent, semi-rusted CDs and blockbuster-rental DVDs, while the recorder will have the noble purpose of backups. Those games that refuse to work without the CD will be shoved down the DVD throat too. Let me tell you, these games can wreck a DVD unit in no time, especially if you play all weekend long. I have wasted some 5 CD-ROM units that way. Should the DVD unit ever fail, you wont be unprotected, since you still have the recorder, and you can wait for the repaired or a new DVD. Think of it as insurance. Battefield 2 now comes in DVD, remember that.
Monitor. If you aint? got space, go LCD. If you ain?t got cash, go CRT. A large, chunky CRT will get you top-notch eye comfort, and spare lots of cash. Any CRT that will give you 85Hz or more of vertical frequency will do fine. LG F700P can do that at 1280x1024, and I know no other CRT that can, with less than 21". Yes, it will drain lots of power. Yes, it will brake your back you haven?t done your weight-ifting regularly, and decides to move it. And YES, it is CHEAP. LCDs will get you rid of your money, for sure.
I guess all bases are covered, I hope I have helped. Good luck, and good shopping.
