strange behavior between same graphic cards.

[0101]

Hi

i bought this system last weak:

CPU: ivy brige core i5 3570k
RAM:4 GB crosair GT 1866 oc
VGA:EVGA gtx 560 ti
MAIN:Asus P8Z68 V pro/gen3
Power: 650 W cooling master psu

my friend has a system with the same graphic card and too lower cpu and ram

but in sleeping dogs game with extreme ani-aliasing his game have 20 frame more than my system.

and in normal anti-aliasing i have 15 frame more than his pc.

i can't understand what happening.

Any idea?:huh:

Just because you have the same graphics card as your friend, it doesn't mean to say that you will get the same performance (although it shouldn't be too far apart). The rest of the computer hardware plays a major part, in particular data throughput. Temperature can have an effect as well, depending on whether thermal throttling has been enabled for the GPU and/or CPU, and at what temperature it is set to kick in.

You could try swapping cards over to see if you get different results.

ok i will test it.
but do you think the problem maybe is power?
is it enough for this system?
