My friends, family, and myself, have been ordering parts from newegg.com for years now. It's a great site, with great prices, and great parts.
I've always ordered parts from websites, and built my own computer. Heres some brand names that are good with some parts.
Logitech makes great speakers. I have the Logitech Z640 5.1 sound system.
AMD Athlon XP's are great processors. I have an Athlon XP 2800.
Samsung makes great monitor's. I have a Samsung SyncMaster 700NF 18 inch.
Creative makes great soundcards. I'm using my motherboard on board sound since it is as good as an Audigy 2 Sound card.
Asus or Abit makes good motherboards. I have an Asus NForce2 motherboard.
Corsair XMS is good ram. I have about 512, but will be upgrading to 1 gig as soon as I get some money.
For video cards, it's really up to you, and reading reviews. Radeon and Nvidia are the two top video card names. I've stuck with Nvidia for the longest time. I currently have a Geforce 4 Ti-4400 128 mb video card. My brother has a Radeon 9800 pro 128 or 256 mb I think. Honestly, I'm not too sure, but his card is really good. You can go either way, Nvidia or Radeon. I'm probably going to end up switching over to Radeon when I buy my next video card, because they seem to be more powerful these days.
As far as cd drom drives, cd/dvd burners, I'm not too sure. You could try sony.
I've always been an AMD type person. You could definitely order intel stuff if you wanted to, but you should definitely choose one type, either AMD, or INTEL, and buy all parts from one....so there aren't any compatibility issues.
If you'd rather not customly build your own computer, and want to just buy a kick ass gaming machine for an all in one package, go here:
http://www.pugetsystems.com/gaming.php - This is expensive, and I know there are cheaper websites out there but I can't seem to think of any...you could go Dell...but I hate dell...hehe.
Most of all this stuff here is just what I like, but it's also good brand names......but perhaps other fellow Avian members here can help me expand upon my info....
