I currently have a Radeon 8500...What I would like to know is...at what CPU speed(stictly speaking of AMD) will the Radeon be a bottleneck? This is a non-overclocked system (133fsb / 275x275)

Thanks for your replies...

You could jump on MadOnion's Online Result Browser and do a search for all systems using an 8500....

Anandtech also had a GPU shootout with a section on CPU-scaling....in UT2003

From the looks of things, 1150-1250MHz looks to be the ceiling for that card...

Hope this helps...

I hear this all the time about bottlenecks.
The truth is if you are running over 1.33 ghz(amd)+or minus some mhz. The video card is still going to be your bottleneck depending on how high you set your video settings. If you play at high rez with aa and aniso turned on even the mighty 9700 and 4600ti still begin to drop framerates from lower rez. And whenever you drop framerate from a resolution change or video option(aa ,aniso) enabled it means your card is limiting you. Now if you dont play at high rez or with aa and aniso enabled the cpu will definitely be your bottleneck.
Just look at benchmarks the difference between a 1.4 ghz machine and a 2.1 ghz machine are minimal when benchmarked at 1600 * 1200 and when aa is enaled its even less.
Hope this helps.
