Yeah but how do you know GPU Shark and Speed fan arn't incorrect. I thought the same thing at first...Hwmonitor was reporting my voltage as 1.212 and gpuz was reporting 1.075, So I tested stock clocks at 1075mV and its perfectly stable with lower temps might I add.

Someone with a DMM should measure VDDC at stock settings with no third party OC apps.

Hey maurauder, i noticed you have 2 7850's in crossfire.
Do you get any bottle neck with your CPU? How similiar would that chip be to the 1090t as far as a possible bottleneck?
post #1554 of 4099
It's a slight bottleneck but i'll be picking up the 8350 once its out. Idk how it compairs to the 1090t as i've never owned one but to give you an idea it scores about 18000 in 3DMark Vantage at 4.8ghz
I can't really test for bottlenecks right now as my second card is not in my system right now. I'll tell you though it's for sure not bottlenecking a single card much

I figured it was some air obstruction resulting in a just the right pitched sound to become audible. This is with both Trixx and Afterburner custom fan profiles (which are identical, but I prefer Trixx now, as it seems slightly more stable).
Thx for reply, now i know there is no need to RMA.

Awesome thread! Subscribed. Just purchased an HIS IceQ 7870 for $199 AR and came with Sleeping Dogs for my spare PC. I believe it is the best bang for the buck card currently available.

I have been strictly Nvidia for a while now so it will be nice to see how AMD drivers have been maturing.

hey guys i recently received my gigabyte wind force 7870 and let me say im blown away by this card coming from an Vapor X 5850 i wasnt expecting the temps to be much better .

. yeah right the 5850 idled around 30C and under gaming load ran to about 60 where as this 7870 idles at 20C flat.. and under the gaming load ive seen so far im yet to see 45+C keep in mind i have not yet set a custom fan profile!!

Thanks smile.gif i just worry slightly because of the thuban's inability to clock much higher than 4ghz, and i want a 120hz monitor eventualy, i figured a 2nd 7850 would do the trick. my board is am3+ so if upgrading to piledriver is what it takes, then that is a possibility in the future.

I read the reviews, I am still not sure, but is the 7870 enough to play BF3 at 2560x1440 with high settings with 2x AA max? I also hear AA isn't even needed on that resolution, what do you guys think?

That sounds about right. And likely you wont need aa turned on. Keep in mind also that overclocking the card should put you in the range of a 7950 which in theory, playing bf3 on high settings seems viable
