fx8350 bottleneck sli 770s?

Hello guys, I'm planning on buying a second 770 because i have a 144hz monitor and I want 60+fps minimum in all games, but some guy told me my cpu (FX8350) would bottleneck the 770s. I currently have the cpu at stock speeds but I can overclock if I have too. Thank you.
 
The FX8350 isnt exactly a speedracer, and its not gonna give you 60fps in all games, OC or not.

However if its worth the upgrade is another case.

Nah, not if your card is OCed good. 8350 770 single should fly, SLI really fly.

But I say wait for the 760 price to come down,
 
60fps min fps in all games you probably would not have even with any x86 CPU with those two NV cards.

I'd say OC 8350 to 4.5-4.6Ghz, buy 2nd card and enjoy.
 
It depends on the game, but at stock you should be fine, and at 4.5ghz or so you should almost never see a bottleneck from an 8350. The very few exceptions may be games such as Starcraft II. As long as you game at 60fps, I don't see any problems.
 
I believe It shouldn't bottleneck if you OC 8350 to 4.6GHz.
FX 8350 is a great processor,and it can oc easily.have fun with it🙂
 
"bottleneck" is a relative term
any given cpu will bottleneck a powerfull card/combination of cards depending on resolution and the game that is played.
the higher the resolution, the more the bottleneck will shift from the cpu towards the cards,--> the better you are with the fx 8350 (when the cards become the limiting factor)
thats why cpu benchmarks are run at those seemingly irrelevant low resolutions, because in high resolutions there won´t be much difference.

the upcoming games that are multi platform with the new consoles should also run good on the fx, as they are probably well prpared for multithreading (new consoles run on 8 core AMD apu, so the games will be optimized for that, or so is the rumour)

i´m running two 770s on a xeon e3 and the improvement over 1 card is fantastic
i´d go for it, it will improve a lot in any case
whether an intel rig with the same cards might perform better is a different story

i also have a system with an fx8350 and 3 hd 6870s (hd6870x2 + hd6870)
that one sadly doesn´t overclock too well (instability)
other than that it runs fine, so multi gpu is no problem for the fx, its platform also has plenty pcie lanes,
which mainboard do you have? does it support the sli at all?
it has to be a 990fx chipset or it won´t,
you can check compatibility on the manufacturers homepage

i´d run a test, but my am3+ mobo doesn´t support sli, even though it does crossfire (890fx chipset)

you could also wait for a r9 290 with a decent cooler, they´re supposed to come soon (early december?)
i don´t know the prices in honduras, but in germany those will be 1/3 more expensive and outperform the 770 by much
if possible, single gpu is preferable two multi gpu
then you build a decent second rig around the 770 and give it to your parents/sister/cousin
or you could sell the card

I also own a 8350 in an Asus Sabertooth 990FX rig. I doubt that 2 770s would bottleneck it. The Intel platforms generally get better fps but 2 770s should handle it in that rig. Did you OC your 8350? BTW, Excellent explanation by BertolomeoDiaz!:awe:
 
FX 8350 won't bottleneck your 770s. Just bump to 4.5 or 4.6ghz and enjoy. I have one and tried 7970 CF before, amazing performance IMO.
An Intel rig puts out better numbers but you wouldn't notice a thing

Thank you, like guskline said great explanation. I have a 990fx asrock extreme9, yes it supports sli.
 
Don't forget most modern games are more GPU dependent as long as you have a fairly recent processor from AMD (X6 Thuban, FX4100 - FX 8350) or Intel Sandy -> Ivy Bridge -> Haswell.

You'll have more than enough for something like Battlefield 4. There are only a handfull of games which are CPU IPC dependent that use less 2 or less cores, Starcraft 2 and World of Warcraft being some of the biggest examples.
 
Are you saying you can't extrapolate if their performance is roughly the same but one needs 20% more clock for that same performance?

Look IMO FalseChristian tried to say that these cpus have identical performance. Let's just leave at that shall we?
 
I thought he was pretty clear in what he said. But if that wasn't what he was saying then why did you try to refute my correction? If your opinion changed since your last post that's fine, just say so.
 
Phynaz i stand by my post. He clearly knows and just chose his words poorly. What you doing right now is taking this thread further off track even after i asked

So do you think a overclocked FX 8350 @ 4.6 bottlenecks a SLI setup??? Answer this or go thread crap somewhere else.

Dude, just admit you read it wrong and move on. It's no big deal, easy to miss a word on the internet. Don't start raging at people who caught the mistake... He said clock-for-clock it is equal to 2500k. Not that it is equal performance. One is a measurement of throughput at an equal clockspeed ("IPC") the other is absolute performance.

Either way, the 8350 is good enough @ Max OC that I personally wouldn't find it worth the money to upgrade. Now if OP has a pretty big budget, then maybe. OP if you are feeling the CPU upgrade itch, you could get a high end air or All in one watercooler and increase your overclock. Then when you do upgrade you can take the new cooler along for the ride
