"This system may have troubles with Call of Duty: Black Ops 2. But with some clever adjustments you may be able to run it."
CPU - 4 out of 10 (grey check)
GFX - 3 out of 10 (red x)
RAM - 6 out of 10 (green check)
Your CPU is probably the bare minimum but passed. Your RAM is good. Your GPU is the weak link and will be the reason if it can't even play at an acceptable frame rate even on the lowest resolution with the lowest detail settings.
So this means i can't play black ops 2 at this specific specs right?
