The CPU may have trouble with 64 players. I would go for a phenom 2 x4 965 BE instead. Then again I'm not positive on how the game is coded.
I had a computer this computer:
Intel Pentium E6300 2.8GHz
Adata 2×2GB DDR2 800MHz
Sapphire Radeon HD 4350
I am not sure what other parts were, but these are three most important for frame rates and I got 20-75 frames per second at the highest settings on a 1360×768 resolution, does that help?
