Is my cpu bottelnecking my gpu?

Pretty balanced system tbh.. it's considered old but it's still more than capable of running games on medium settings at 16x9 resolution.

emm..

if its blanced why do i get low gpu usage?

i am planing to change my cpu from dual core to core 2 duo (heard they are much faster)

what would be the best choice (dont need more than 3.2 ghz )

What kind of settings are you running those games on? Also, is that a recorded sample of your GPU usage as opposed to alt-tabbing the game and then checking?

"Bottlenecking is a misnomer. There is always a slowest component. If you replace the slowest component with a faster one you just created another "bottleneck".

It should be good, my friend has a e5200, the one belows urs and i think a 7750 wouldnt bottleneck with it so maybe im guessings its 2gb of ram, most modern games recommend 4gb, im not sure if this would cause low gpu usage.

I bet your cpu runs 100 % to try feeding your gpu - so changing to a faster cpu should give better gpu usage . You should be able to find a Core 2 Dou like E6600 (2.4 Ghz) or E6700 (2.66 Ghz) or a Quad-core like QX6600 (2.4 Ghz) or qx6700 (2.66 Ghz) and allso change to Win 7 64 bit would help

thank u guys for replaying ..

at all settings the gpu usage is low and i use msi after burner for monitoring in game gpu usage and fps

i think 2 gb is enough with win xp and i cant install seven it will use about 1.5 gb of ram so will lag all my games

and my cpu runs at 100 % thats right so it's actualy slowing m gpu BUT are u sure e6700 will be enough?

oh i just now tested assasin creed brother hood and found 90 % gou usage  

i think that games that need high cpu usage slow my gpu cuz the cou is fully taken and
cant handle my gpu (brother hood is running smoth on almost maxed out setting except for shadows and post effects)

Notch the graphics up to medium or higher and check. Low settings put most of the load on the CPU.
