Adding another Gtx 780SC ACX for sli with i5 3570k 4.2Ghz worth it?

[SilkySkills]

Hello new to the forums hope you're all very well, my name is Mike and i was thinking of going sli in the future but wondered if it would really be worth it and if I'd even see a difference?

I get 70-120 fps on Bf4 on ultra and wondered if i would get decent performance without my Cpu having a melt down from raw Gpu performance?

 

I'm mainly worried the i5 3570k wouldn't be able to handle it.

I think it should be more then fine

Someone said i would have to upgrade my Psu to a 850w if i went sli, is this true?

Well it depends....If you want any head room.....I would go to 850w just to be safe!!

 

Sorry I missed looking at your psu

That's cool.

I thought i already had headroom with the 750w as i've seen people using 600w power supplies for the same sort of builds.

750w is enough for SLI

What do you mean you don't think it'll handle it?

I thought i might need a more powerful Cpu because when i play Cpu heavy games like Bf4 it might restrict me getting the most out of my Gpu/Gpu's

[Thunderjolt]

You processor will be plenty fast to run SLI.

Good to know. I'm mainly looking now so at some future date when the Gpu is at a good price i can get it and get some nice performance

Everything restricts everything. If you had a GT 210 in one system with a pentium, then the performance would be less than one with an i7 4770 in it. Bottlenecks don't really work the way that people think. Even though the bottleneck was the Graphics card, there are other factors in play all of the time. JUST YOLO IT.

 

[However, an upgrade to Haswell won't go amiss]

Yea i get that you will always get a bottleneck somewhere, i just hoped that adding another Gpu with the i5 3570k would add more performance. Btw  I love your picture.

Yeah, I'm sure it'll work out fine

 

And thanks

Check power consumption with a program, and if you want to over clock use your program to decide.

CPU Bottleneck alert.

 

I would step up to a Haswell i7 OCed to 4.4 or a little more if i'm even remotly considering such a GPU upgrade.

 

Although, waiting for broadwell might be a safer bet, since actual boards don't support it. (it's way muddier than the last time around when even sandy bridge intended boards ran ivy bridge perfectly well)

theres not alot of merits going with a i7 for gaming, and the difference beetwen haswell and ivy is like what .. 10-15%? even less if you overclock properly? so that's like what .. a couple fps ingame?

theres no "cpu bottleneck allert", yeah two 780's is abit much but he shouldn't worry about it.

i7 don't contribute much to gaming performance... when you only have one 780, by pushing more graphics horses the CPU needs more threads to spare, and that's what the i7 offers.

 

Unless you want him to go totally overkill and grab an i7 LGA 2011. ^^

 

This myth about i7 not contributing much to performance is only valid when the graphics power need to power a given game isn't huge, in this case it's enormous, two of these can basically run CRYSIS 3 at almost 60FPS in 2.5k, i'll let you imagine how much processing power is needed to achieve this...

[silencerbob]

if you got 1440p with your monitor I highly recommend a 2nd gpu..like me =)

it's a simple fact.. most games don't take advantage of hyperthreading, some even have a performance decrease.

and did you miss the part where i said the difference in performance is minimal?

and lga 2011 is obviously pointless, the truth is for gaming theres nothing that's actually much better than a 3570k.

[SilkySkills]

It seems to be an issue that everyone has a difference of opinon on, i wish linus would do a video on it because the i5 3570k/i5 4670k are popular cpu's and the 780's are coming into peoples price ranges now. Everyone always advises everyone else to get i5's and when somebody want's to sli everyone say's you need an i7, that's a bit of a pain tbh, they should tell them that an i7 may be needed if they want to sli in the future.

You'd be surprised if we actually put the facts you're claiming in test. ^^

 

The 4 extra threads aren't just sitting there doing nothing, these are extra ones that offer performance improvements over the regular i5 in CPU Bound situations (where GPU ressources are heavily sucked in balls to the walls)

This is actually one of the main reasons i hated the "How many CPU Cores do you need for gaming ?" It featured a GPU barely capable of leveraging those extra cores.

 

If he can do one with two GTX 780s, we'll know the truth for sure, while i'm at it, @LinusTech , are you planning to do a such video ? (i've mentionned him, he should be notified)

If he does do a test he should also  try it with the GTX 780SC ACX, Titans and the 780 ti's

Or pick the fastest ones and figure out the performance deficit from there, easy money.
