Pentium D 3GHz
2GB DDR1 PC3200 Dual Channel
250GTS 1GB DDR3 Dark Knight Edition
Intel Mobo lol
Windows 7 Ultimate

Didn't check the FPS, but on Ultra Setting, a lot of jerky movements.
High settings a bit jerky but playable on Campaign, not on those mission that have lots of units.
Low settings is smooth, but massive unit missions will still slowdown the game including multiplayer especially 4v4

Resolution is 1280x768, 1440x900 can play oso but i reduce for playability in multiplayer mode.

Definitely need to change my mobo, proc and ram
