Will the bottleneck be horrific?

[garylopl]

So I recently just bought an AMD 6870 while I was on vacation, and I was thinking. Will I be bottlenecked from my AMD 925? I have it at stock 2.8ghz, quad core. How bad do you think it'll be?

Depends on the resolution.... Below 1920x1080 it might be significant. From my memories a 3ghz AMD bottlenecked a 460 and the 6870 is faster.

I would try some games out instead of asking on the forums since I'm just guessing and I'm guessing not many review sites actually try this kind of stuff.

is it AMD Phenom II X4 925?

I would try out games, but I'm on vacation away from my computer. To renz, yes indeed!

I'd suspect about 10-15% lower framerate than could be generated by X4 at 3.3 Ghz, but, as long as near 30-60 fps, will certainly be playable.

the easiest thing you can do is looking for review. i believe most reviewer will use setup that will not bottleneck the card they test. try looking at games that heavily dependent on gpu such as crysis. if your frame rates are close to the one done by the reviewer then it means you're fine. but if your frame rates are significantly lower than theirs then it's time play around with your cpu clocks

Nobody can answer your question without knowing what resolution your using.

 

[garylopl]

That'd be 1680 x 1050 :O!

If you play with v-sync on, it won't.

At that resolution, yes there will be a small bottleneck. You can test this by overclocking your cpu to 3.2ghz and comparing benchmark results with the cpu at 2.8ghz.
