LOL, call it researchJulio, how do you have time to play WoW and run a website dude ? You know there isnt much time left over for less important things like work, showering, laundry, healthy meals or sleep when you start playing WoW
I have friends who I went to the local Wal-Mart with, they purchased WoW and I never seen them again....weird.
I understand server lag issues and crappy isp issues but im putting those obvious and unavoidable things aside.Wow isnt the most demanding game and I know lots of people with it cranked up with less than performance computers.
The biggest thing you need to know when you say "without lag" is that most lag that you are going to get on wow is server lag from what I have heard. Even the guys that I know with boss machines that play WoW still get a lot of lag especially during huge raids. A good internet connection with a decent upload is probably your first upgrade to keep in mind.
Technology
What are the system requirements?
PC System Requirements
OS: Windows 2000 (Service Pack 4) or Windows XP (Service Pack 2)
Processor: Intel Pentium3 800MHz or AMD Athlon 800MHz
Memory:
Minimum: 512 MB RAM
Recommended: 1GB RAM
Video:
Minimum: 32MB 3D graphics processor with Hardware Transform and Lighting, such as an NVIDIA GeForce 2 class card or above
Recommended: 64MB VRAM 3D graphics processor with Vertex and Pixel Shader capability, such as an NVIDIA GeForce FX 5700 class card or above
Sound: DirectX-compatible sound card
So what I would suggest is for full detail would be:
Video: Nvidia Geforce 6600 128mb or better
CPU: Just about anything over 1.5ghz by todays standards will do.
RAM: 1GB will probably suffice but with DDR2 running as low as $30 for 2gb, why the hell not go with 2 gb ?
