And give a brief explanation of your in game performance.
Date bought: Early 2005, (for WoW ironically).
3.2 GHZ P4 Processor
2gb DDR2 Ram
Radeon HD 4650 1gb
(Has been upgraded twice, was originally a 6600GT)
Windows XP Pro
I used to be able to max WoW back in the day but now I run lower medium settings with 720p resolution. I get 25-50 fps in most of the open world of Cataclysm probably averaging somewhere in the upper 40's. In excessively crowded areas such as major cities during prime time and 25 man raids my FPS can drop as low as 10-15, a little choppy but still quite playable.
Overall I would give my system performance a: 6.5/10
Its an old pc and the game is fully playable, but it doesn't have the power to turn things up anymore and gets choppy with with excessive amounts of players on screen.
