5770 -> 5870 not so huge an upgrade, is it limited by cpu?

[poohbear]

Hey all, so i upgraded from a 5770 to a 5870, but the difference in FPS isnt exactly shocking, its only gone up 10-15fps in the games i play, with the exception of some FPS games were the change was indeed shocking (AvP went up 40-50 fps). But the games im currently playing often, Dawn of War2 (only 10 fps diff with ingame benchmark), metro 2033 (10-15fps difference), have'nt shown a dramatic improvement. The biggest difference ofcourse is when i turn on AA, the 5870 hardly flinches, but my 5770 would choke.

Without AA, is it because the 5870 is bottlenecked by my cpu?(full system in specs) I doubt it as im running it @ 3500mhz, that should be able to feed the 5870 no prob right? I game @ 1920x1080. Cheers and thanks in advance for any feedback.

Yeah turning on AA will make the difference between the video cards greater just like increasing the reolution.

For Dawn of War II i'd imagine a CPU upgrade is needed to get the FPS boost you desire. For Metro2033, what was your starting point for the 10-15fps increase? Given Metro2033 demanding nature I'd think a 10-15fps increase would be a 50-75% improvement from your 5770.

There is probably XX% with the tri-core VS phenom II quad, and the slower ddr2 vs ddr 3, is probably x%.
Did you uninstall the AMD driver and reinstall ? Even though same company, device ID effects installation.

I think your cpu might be bottlenecking this slightly, but what you can do is turn up the eye candy, so in other words, if you cpu keep the game down to 30-40fps playing medium graphics setting with no AA/AF, now you will still get 30-40fps except you can turn it up to say very high setting with AA/AF. In this way you gpu power is never wasted, just used up via better graphics.

What resolution?

I doubt your CPU is bottlenecking you

This.

You haven't given us increases in percentage, which is the only thing that matters. According to Anandtech, at your resolution, a 5870 should get exactly 13.5fps more in Metro2033 than a 5770: http://www.anandtech.com/show/3987/...enewing-competition-in-the-midrange-market/11

So you got what you paid for.
