Hi, I currently play FF11 and have been thinking about quitting for a few months now. I was not planning on getting a new MMORPG I always said "FF11 will be my first and last MMORPG" but I have read some reviews and saw some movies(love blizzards games also) and WoW has drawn my intrest. Now I played FF11 on my PS2 because my old comp was well old... anyway I just got a new comp 2 months and am hopeing it can run WoW with out problems I am not very computer....smart so please help me out:

My Computer has

Emachines T2862
60 GB Harddrive
256 MB
Intel Extreme Graphics 3D
2.67Ghz Celeron D processor

Could that run the game decently? Thank you for your time :)
