Bottleneck

[Terrier_Jimlad]

Would this spec bottleneck adding another GTX670 2GB OC (running stock) in SLI?

i5 4670k @ 4.4Ghz
Gigabyte Z87 G1 Sniper
GTX670 2GB OC
8GB 1600MHz (9-9-9-24)
Samsung EVO 250GB (with RAPID mode)
Corsair HX750

Appreciate your comments.

Yes, I think you would get some form of bottleneck. You may experience up to 70% usage on both cards with an i5 and an i7 would give up to 90-100%.

yes in some games. My i5 (2500k) bottlencecks my SLI 670's in parts of Crysis 3 and also in Battlefield 4 with lots of players (only get 65-85% usage in battlefield 4 on both cards)

If there's a bottleneck it would be insignificant. I'd go with 670 SLi without a blink

I doubt you'll run into a bottleneck with 2x 670's on those CPU clocks.

That'd make Sli impossible for most users already, and people do it with much higher cards. The difference between 4670 and 4770 isn't that huge.. and some are using older gen CPU's.

Now tri-sli, you'll see the bottleneck.

Definite bottleneck in some games ( Crysis 3 and Battlefield 4) Well documented and ive experienced it myself with a 2500k and 2x 670's. Rome 2 also has a massive bottleneck but that is mainly because the game is so badly coded even a 4930k at 5.0ghz cant run it properly.

There shouldn't be. If there is, clock your 4670 a little higher.

There is. No clocks are going to make up for the fact that some games (especially Battlefield 4) use 8 threads/cores much better than 4.

I get 65-85% usage on my 670's in the beta. People with i7's and 670's are getting 95%+ usage

Actually thats not true my i7 2600k runs fine on BF4 only at 50% where as i5's even newer have issues. And no my i7 isnt 8 cores.

No but it's 8 threads.

Im not talking about cpu usage and an i7 has 8 threads as i wrote (threads/cores)

Don't compare the poorly optimized BF4 beta to anything when thinking about current hardware purchases..

Just remember the super-buggy BF3 beta, and see how well it runs now.

You can find reviews of several cards in SLI where a regulat 3xxx 4xxx CPU is being used. If a 4670k was not powerful enough at 4.5ghz to run even 2 old-ish cards (GTX 670), how the heck could anyone ever run tri-sli with any CPU? Or Quad-sli? Or 2x titans.

And now for the old argument: 3x 780's in 8pack system powered by a 4770k with a slightly higher clock

Except BF3 does the same (to a lesser extent) and so does Crysis 3.
