so after playing crysis 3 for a day, I have realized a single 7870 isn't going to cut it. even overclocked I get dips into the lower teens and twenties. anyone here have a crossfire setup of 7870's or 7850's that can share their results with crysis 3?


I was thinking of getting a Tahiti 7870, but then I wouldn't be able to crossfire, also two 7870's will outperform a single Tahiti you.

what do you guys think?

I was able to get a second Diamond 7870 reference card last week for a rather good price. The performance is notacible. I don't have crysis 3 , but did manage to get Battlefield 3 a few days ago with EA 70% sale and i can max out all settings on Battlefield 3. I did get better performace once i installed the cap profile update from ati . It really is important what driver is being used. They have had allot of revisions past few weeks.

Mattb2e i play crysis 3 over 60fps in high settings my 7870 is at 1200/1450 with 2x SMAA if you use more then that your FPS drop a lot.

If you want to upgrade from a 7870 dont go for a 7870XT at least get a 7950 boost.

You can almost max out BF3 with a single 7870, which was the entire reason I went with one in the first place biggrin.gif. I am still curious to see your results though, if your willing to post them.

Unfortunately, my card does not clock that high. If I remember correctly, the highest I was able to get stable was 1150/1450. Even still, overclocked at 1100/1450 I get drops every now and then, at high settings with 1xSMAA. The max FPS aren't the issue, its the minimum i'm concerned with. Once you dip below 30, things become alot less fluid.

In terms of an upgrade, I know an HD7950 would be nice, but a second 7870 would perform better than a single 7950, or even a single 7970. Although, then I run the risk of added headaches with microstuttering and what not. Which is why I am posting here biggrin.gif. Im hoping that someone can share their results with me to sort of justify the purchase biggrin.gif.

I haven't tried overclocking since 12.8, so it might be worth while to give it a shot again.

If you can go for CFX the drivers are better everyday the13.x are 10 times better compared to 12.x drivers.

When you were overclocking did you upped the voltage? From what you're saying it sounds like you're overclocking without a voltage bump up. I get the same stats if I overclock with stock voltage but if I up the voltage I can get way more performance out of the card. Right now I have the GPU up to 1225.

I got almost another fps with the new 13.3 b3 driver 1150/1400 clocks (msi tf3 7870 ghz ed.)

What is the safe area for voltage on these cards? Might have to see what kind of clocks i can really get out of this gem.thumb.gif
