Black Ops running laggy on my system

[sic6six]

ok i had black ops for my birthday this year and have tried to run the game only to run into system lag on the single player mode.

My system is as followed

CPU: AMD Athlon 64 X2 5000+
Mobo: Gigabyte GA-M55PLUS-S3G
RAM: 4GB (Win7 saying 3 usable) (Dual Channel)
GFX: NVIDIA GeForce GTX 285
PLENTY OF HDD SPACE (so thats not an issue)

Nothing is overclocked as i dont know the best way to overclock and dont wanna do it if it is not needed.

Anyone have any ideas about what can be causing the freezes in game.

ah good im not the only one. thought it a bit odd considering it looks like the graphics are the same as mw2.

i tried oc my machine but wouldnt know where start properly in order to get the desired result.

will wait for the patch i think and see if i can slowly save to buy the needed components for an upgrade. boy this could take a while.
