Will my cpu be bottlenecking my gpu on these specs

AMD athlon ii x645 3.1ghz quad core
MSI AMD readon twin frozr 7950 hd
8gb ram
600watt psu

On novabench I'm getting significantly lower score on gpu than comparable people so will it be bottlenecking and if so does anyone know the over clocking potential of my cpu?
 
its the cpu dude... i run the athlon x4 640 and i only upgraded to a gtx560 as thats the most i would put with that processor...

if you cannot upgrade, overclock the processor to 235 on the bus speed which should make it 3.5ghz, up the volts by one notch and lower the HT to 2000mhz... that will give you an extra 2ghz of speed over the 4 cores... this should help a bit
 
In my opinion it's quite embarassing saying "bottlenecking" one by another - like CPU had no enough power to make GPU working faster. GPU works anyway at the same speed (no magic MHz boost, except Turbo function in newest nVidia cards), and if you can see different benchmark scores regarding to the same graphic card - it means benchmark cannot be trustful, or people should do it using the same settings @ whole platform. Such story was popular with 3DMark06, which was CPU-dependant no matter which GPU you had - simply saying: different CPUs gave different final scores. I'd like to underline: nowadays CPUs are quick enough to fulfill GPU & buses requirements, otherwise you'd get significantly better GPU-based scores using better CPUs, and significant GPU load was higher in case of using better CPUs. This is not happens.

Another thing is adequate CPU for software you are using - and this is correct point of view people should stick with, in my opinion. Requirements on DVD boxes must be re-calculated using own calculations (depending on resolution you play, for exaple it's good to asume they give you recommended hardware reqs for 1024x768 resolution, so find a factor that your resolution is bigger - for example 1.5 and multiply GIVEN theoretical card compute performance by this factor and you've got compute performance of card you are just look for; similar calculation you should do for CPUs). Benchmarks are not worth much.. except someone (like anand, toms and others) makes it constantly on the same platform, with same settings.. and using proper code that is able to measure GPU efficiency independent on CPU one (as one of many results, BTW). FOr your info: even novabench website is not displayed correctly on my linux, so how they can be serious ? ;)
 
dude, if you don't have the right pairing between cpu and gpu, you will get a bottleneck... i.e putting something like an athlon x2 4000+ with a gtx680... its common knowledge dude... a gpu like that with that processor, you are bound to see a bottleneck in speed and performance
 
Biruo what are you on about?
A computer only works at the speed of its slowest component. Which is why that CPU will bottleneck the GPU, because its slower.
 
altho biuros post i didnt understand at all lol i will say a couple things mentioned, resolution and standard settings benchmarks use

example, if i run at 1900 with AA and all the extras, capped at 100fps maybe my gpu is maxed but my cpu isnt
then i run at 1600 with no AA capped at 150fps my gpu is maybe at 50% but my cpu is maxed

the bottleneck will depend on what you are trying to achieve and not everyone uses typical settings ><
