Gtx 670 sli can be bottlenecked by i7 3770 ?

i bought non K version so i can't overclock my cpu .... so i want to know can my cpu bottleneck 2 GTX 670 in sli ??

 

[toyota]

yes it can but only in some games and it also depends on settings and resolution. and why on earth would get a non k cpu if you were planning on running a high gpu setup like that?

 

[brandon888]

toyota

im just asking and i got non k version for the best deal 200$ so ;/ ......


resolution is 1920X1080 ....

any onther information that you need ? i can write no problem ...

 

[toyota]

well that deal is going to hurt you a little now with a high end sli setup and even more on your next high end sli upgrade.

why do you want to fool with 670 sli at just 1920x1080 anyway? I dont really think its worth the hassle at that resolution.

ok .... then i will wait for 780 ;/ or 800 series with ICPU .... maxwell .. then no problem with cpu bottleneck .....

There will always be a bottleneck, one way or the other. However, the question is how big it is.

The bottleneck for i7 3770 and GTX 670 SLI will be very minor, and not very detectable in normal gaming scenarios.

 

[brandon888]

The_Golden_Man

minor like ? i mean for example 100 fps vs 110 ? average or more ?

Hard to say excact, but in bencmarks like 3DMark11 you will score a little lower, but for gaming I think it will be very minor, at least at 1080dpi and up. The i7 3770 has a Turbo frequency at 3.9GHz. That's pretty high for a stock CPU. I think most people don't run much over 4.5GHz on the K CPU's anyway. Not going to make a world of difference.

 

[brandon888]

The_Golden_Man

yeah in 3D mark sure i know i will get lower score then on gtx 670 sli ..... very minor bottleneck is nothing thank you

If you look in my signature you will see a 2600K@4.4GHz and ASUS DC II GTX 670 SLI.

Yours in SLI and at 3.9GHz will be about the same speed as mine. Yours has PCI-E 3.0 (assuming you have a pci-e 3.0 motherboard) VS mine at PCI-E 2.0, and you have an Ivybridge, which will add a little performance boost over Sandybridge, per clock that is.

So you'll be fine with GTX 670 SLI. Also, it is not overkill for 1080dpi or 1200dpi. I game at 1920x1200 and see the benefits of SLI in many games.

 

[brandon888]

The_Golden_Man

yes i have Z77 mainboard so it supports pci 3.0


yes cause single 670 got dips below 60 in gmaes like crysis 2 or bf3 and more with 2 gtx 670 u will be fine and always will have 60+ fps


and i got same RAM as you ...

Corsair Vengeance 1600 9-9-9-24@4x4GB

but only 8 gb .. i need more then 8 gb for sli setup ya ?

8GB is fine. Only reason I have 16GB is because these sticks was on sale for a very low price. You will have no benefit going past 8GB for gaming and regular use.

 

[boxleitnerb]

Strongly depends on the game. There is no right anwser. But what I can say with absolute certainty: There will be a bottleneck in some applications.

My suggestion: Live with it or up the (driver) settings (AO, SSAA etc.).

 

[brandon888]

boxleitnerb

appications ? don't care


games yeah ... some use cpu too much some don't ... for example skyrim usess cpu a lot ... bf3 is more hangs on gpu and so on ...

 

[The_Golden_Man]

A 3770 at 3.9GHz cannot be considered a bottleneck at all. AMD Phenom's, even at 4GHz + is a bottleneck for gaming. But not as long as you are at Sandybridge or Ivybridge technology, atleast if 3.5GHz +.

As I've said, there will always be a bottleneck in any system. In one way or another. The question is how big it is. The smaller the better.

But saying an Ivybridge 3770 at 3.9GHz Turbo frquency is a considerable bottleneck for GTX 670 SLI is just not true.

 

[brandon888]

The_Golden_Man

agreeed .... and anyway dude ... sli with 660ti does not worth ;/ so best performance/price will be gtx 670 in sli .... 660ti is bad card with only 144 gt/s memory ;/

and yes .... for example i7 950 on 3.9 ghz is not same as ivy on 3.9 ........... ivy is faster .... and amd processors are even worse

 

[hokies83]

After 4.3ghz i no longer seen any bottleneck from Overclocked SLI 680s

Your card boosts to 3.9ghz which is = to 4.2ghz SB + all the features of IB..

If you are bottlenecking it is a very very tiny bottleneck if any.

i think you meant cpu not card but anyway if there will be tiny bottleneck .. then who cares ? even if -5% fps ? meh ....


yeah i sam even i7 950 on 4.2 with gtx 680 sli and there were 99% gpu usage in BF3 and 89-99% on skyrim

I meant games. BF3 is very CPU dependent in multiplayer. Skyrim, the Total War series are heavy on the CPU. Additionally, if you need for example 120fps (vsync) in a shooter or racing game, a strong CPU bottleneck may also be introduced where you would not assume one.

I would keep the CPU - there isn't that much out there that is alot faster. But next time spend the extra bucks and get the K model. Higher resell value, too.

you will probably see a harder drop in minimum fps vs an overclocked 3770K

 

[brandon888]

BTRY B 529th FA BN

oh really ? i know that OC cpu is faster than stock .. it's like 2X2 =4 ....

boxleitnerb

who said that i need 120 fps ??? i need only 60 for games .... i don't use #d or 120 herz monitor ;/

i saw video with gtx 680 sli on i7 950 4.2 ghz .. do you think old i7 950 4.2 is faster then ivy with 3.9 ???? and that guy got 110+ fps on bf3 ;/ i think there was not any bottleneck ....


skyrim and total war ? maybe .. because they are bad optimized .... games must be depend on gpu mostly then on cpu ......



look at max payne 3 !!!!! even with I3 2100 you cna run with gtx 680 and have 80 fps with no AA !

that is what im talking about

 

[BTRY B 529th FA BN]

if you had a MicroCenter near by you could of got the 3770K for 259$

i might just get one and resell it

have a good day

K version costs 100$ more ....

and how do you think .. your i7 920 on 4.2 ghz can own 670 on sli and mine non k version with 3.9 boost can't do this ? i just want to know ....
