CPU bottleneck?

[refhat21]

I am wondering if my CPU gonna bottleneck my system if i add another graphics card.

I have CORE i7 920, 16 Gb of ddr3 ram, GTX 780 and 850 watts power supplies.

no, not really.

[dragoon20005]

the i7 on the LGA 1366 is still a very good CPU

 

just OC the CPU

 

and for the GPU

 

if you are using the GTX780 3GB version

 

the second card has to be a GTX780 3GB also for SLi to work

[lani100]

 No! you should be fine.

what resolution are you playing your games at?

[refhat21]

My CPU already overclocked 3.2 ghz do I need to overclocked further? My resolution is 1920 by 1080

it will definitely bottleneck like crazy.

Because every cpu will bottleneck dual GTX780´s at 1080p, in cpu boand games.

 

You wont get anywhere near 100% scaling at 1080p in cpu bound games.

No matter which cpu you trow at this.

I wanted to upgrade because I am getting only 25 to 35 fps in dragon age inquisition so I thought maybe if I add another 780 that will boost the fps plus I am gonna get Witcher 3 as you all know witch 3 will need more graphics power to run smoothly.

Yes offcourse you will still getting a performance boost from a GTX780 Sli offcourse dont get me wrong.

The performance increase will be significant in terms of pure fps numbers in some situations.

 

But like i said, on 1080p in cpu bound games, you wont get the full potentional out of that gpu setup.

No matter which cpu.

No full potentional, or lets say, no 100% scaling, to stay in technical terms.

 

I do see people state "that there wont be a bottleneck".  But thats offcourse wrong.

no this is because your CPU is crapping out...if you want epic performance in that game you'd need an overlocked haswell core i7 CPU that's what i'm using and i get above 55FPS on nearly max settings at all time with a single GTX 780 mate.

A single-high-end GPU for 1080p is perfect and should offer you very good performance in just about any games really...i run a GTX 780 personaly and no games as of today can bring this gpu to it's knees like that.

Monitor your GPU loads with MSI afterburner to confirm the bottleneck and if you don't get consistent 95%+ GPU loads in games with vsync off then yes right there something is limiting the cards potential.

 

3.2ghz is a low clockspeed by today's standard and your CPU is like 4 generations old by now...it could be much better.

Haswell i5 and i7 cpu's have a substantial IPC increase that has occured over the years making them noticeably faster AND they also have much increased clock speed over first gen i7's like yours...

Your CPU has released in novemeber of 2008...it's really starting to show it's age when paired with high-end GPU's like that playing modern demanding titles...sure.

I see,Thanks guys for your input.

IMHO you would benefit a lot more from a platform upgrade than you would spending 300$ on another 3GB graphics card...do you happen to live near a micro-center?

[Tasuma]

Instead of getting a 2nd 780, could you maybe get a 970? I think it is a better card and if you are only going to be playing at 1080p it should be able to run everything just fine.

..and so does a GTX 780!

not worth it at all mate the GTX 970 is only around 12% faster than a GTX 780 tops...there's no worthy upgrade to the GTX 780 as of now...i know otherwise i'd have it...well unless you consider an upgrade to a GTX 980 ''a good way to spend 600$'' there is not upgrade yet.

[refhat21]

I was thinking about going microcenter today but I now I don't know.

[Midnight]

One 780, no problem. Two 780's, I'm not so sure.

[i_build_nanosuits]

They have insane deals on motherboard + CPU bundles...i'd suggest you get this:

 

 

If somehow you want to spend 80$ more you can have the i7-4790K and the same motherboard if you think it benefits you in the long run to have those extra CPU threads.

309$ for this motherboard and CPU is a steal honestly, you won't find better deals for sure.

Unless that one more GB of VRAM means that much to you. At higher resolutions, that might be a deal-breaker.

Thats a pretty damm good deal ye, definitely.

 

Why dont do i live in the States lol...

[i_build_nanosuits]

Here benchmarking done with an haswell core i7 and a GTX 780 in that game at various settings (same config i use, even the CPU is clocked the same i run mine at 4.2ghz)...i've found these to be very accurate and in the ball park of the performance i get out of my gaming rig (specs in signature) if your's doesnt run this game at this level then i have no choice but to point at your CPU honestly.

 

[refhat21]

My original plan was wait until my current system dies then get haswell core i7-5820 with 16 Gb ram and transfer my graphics cards to the new system. That's I was thinking of getting another 780 now put them in sli and use them later system.

nahhh man.. IMHO 3GB of VRAM is just too little if you start monitoring VRAM usage in latest games you'd quickly realise that most newer games cap out or nearly fully use all your 3GB of VRAM for 1080p gaming is you use high texture quality and nice anti-aliasing. VRAM won't add up in SLI.

Also the 5820K is not worth it for gaming you get 2 extra cores that won't be used by games for the most part and the motherboard and DDR4 RAM will empty your wallet and you still have to overclock that CPU to match the 4.0ghz and 4.4ghz boost i7-4790K in gaming for example.

I think what you should do is get the i7-4790K and MSI Z97 gaming 5 or asus Z97-AR for 389$ and wait for real next gen GPU's to hit the market and pull the trigger on a single more powerful 6GB GPU when available...a single GTX 780 still max out most games at 1080p ultra 60FPS honestly.

[WaitForMeImOnDialUp]

get the second 780 if thats what you want, you can always upgrade platforms later and still have 2 badass gpu's.

 

also a thought, if you happen to have a x58 motherboard...i'd say get a x5650 for 70 bucks and oc the crap out of it.

[refhat21]

Isn't getting 5820k would be more future proof then 4790k? Also I noticed in dragon age my system vram use about 2200mb.

[i_build_nanosuits]

by the time games succesfuly make use and get noticeabe performance increase from 12 CPU threads the 5820K will most likely be irrelevant as there will be faster CPU's out there with higher IPC and faster clockspeed already...IMHO no the i7-4790K is as high as you should go even with ''future-proofness'' in mind.

 

You might want to hold until intel release new CPU's with greater IPC before you buy though, because X99 is the same performance as haswell Z97 when it comes to gaming the CPU's performs the same pretty much the multi-threaded performance is better for content creation and workstation type of applications on X99 but for games it's not worth it and most likely will never benefit you very much even looking far into the future...that's my 2 cents though i might be proven completely wrong in 2 years from now who knows but i highly doubt it...a stronger hyper-threaded quad core from the next generation of intel CPU's for example should play games better than the ''old'' X99 6 core CPU.
