No you will have no issues as long as you are overclocked.

 

Even if it's not you'll get exceptional framerates.

have a friend with an 8320 and a xfx 7970. set him up last week. i bought the 8320 cause he's live streaming, more cores are more helpful in this instance.

 

Thanks for the help you guys, I am off to purchase my 7970 now

 

what about 2 7970's? will there be a bottleneck? i just picked up a 8350 and wanna get another 7970

*srry to hijack thread lol*

Don't do xfire with amd cpu. 1 card fine, 2 is a no no. Speaking from personal experience.

 

can you please elaborate on that?

Maybe he means that some games perform better without xfire than with it.

 

I believe that the SB950 (Southbridge) of the 990FX-970 chipset motherboards can't handle two or more GPUs very well, making a bottleneck.

Probably depends on what game you are playing. The FX-8350 just isn't enough to let 2 7970s let loose. Battlefield 3 is ok, Skyrim No, and F1 2012 no.

If BF3 is ok then you will be fine with 90% of all games with xfired 7970's and a 8350. if the game is coded well then your GPU's should still be the bottleneck. Skyrim is a very CPU dependent game and doesn't take advantage of all 8 threads so performance vs 3770k suffers.

 

hello,
bf3 uses six threads to run, and I have had it running alright with only 2.8ghz clock, so no, I don't think two of the best bits of kit on the market will bottleneck it.

Just one example. AMD cpu overclocked is on par with an i3. You will see a big difference between intel and amd with xfire.

My old thurban at 4ghz was brutal bad with 5870s and 6950s in xfire. Only realised how bad it was when I moved to a 2500k. You will not be able to get the most out of both gpus, heck even on one gpu you will be behind anyone with an i3.
Stick with one gpu.

i looked over that article it is a load of rubbish.

 

It will not bottleneck it at all. Especially since it runs at such a high speed.

I saw a guy running THREE 7970's perfectly fine on his overclocked 8350. It is a serious performer.

 

lol..the 8320/8350 are more comparable to the i5 than the i3.

You will not be bottlenecked, As stated above, we have seen tri 7970's running perfectly fine on an 8350.

 

I actually went ahead and ordered one about an hour ago or so, went with the sapphire vapor x 7970. Looking forward to it and that deal they had, crysis 3 and bioshock infinite included is such a steal!

 

I can't believe how little some people know and try offer advice? That or they just troll. Xfire doesn't work on f1 2012 not because it has an amd cpu but because the game does not support it, you will get flickering and lower frame rates with amd or Intel...

Also you will not get a bottleneck with an 8350 and 2 7970's, much to most people's disappointment the 8350 is very similar to a 3570k clock for clock in gaming

AMD cpu and CF or SLI is a NO NO.

Dream on.
I am not going to get into an argument about "I know this person and it works"

I had a phenom II 940BE and a Thurban. Fine for single GPU, crossfire is a waste of money.

I suppose you have a friend who knows different though.

the FX 83xx won't bottlekneck 2 7970's on it's own it's more then capable of running them to full potential.

the SB 950 chipset doesn't have enough bandwidth to do it, The hyper transport can't supply 1 x16+ 1 x8 bandwidth let alone 2* x16

If only the 8350 was on a better chipset.

if it were 2 7870's it wouldn't be a data throughput problem and as such the 8350 would be a great chip to crossfire or sli on

 

someone on OCN is using the 8350 and 4 7970's and is managing next to no bottleneck, it's interesting at least to me

but for 2 7970's? i don't really think it will given that other people are having next to no trouble using that configuration

Oh yes I'm sure they run without problem, but if he put in an i5 there would be a big difference in performance. Running high end gpus on amd is a waste of money.

Fanboys don't normally bother me, but when people are giving out bad advice out of loyalty to a brand then it's a step too far.
You could learn the hard way and try AMD cpu then an Intel and see for yourself OR you could ignore the charts above and rely on what a friend of a friend says.

Stick with 1 gpu is my advice.

Maybe amd of old but the 8350 is fine read the source i supplied, i did this thread because i was sick of the bs floating around, i noticed massive differences of what review sites said an 8350 could do to what i was getting. the sad reality is that the majority of review sites are sponsored by intel and get paid to do the review... An impartial review goes out the window at this point...
