Bottlenecking with New GPUs?

[bobbyincide666]

Hello All! I am wanting to get ready for Battlefield 4, CoD Ghost etc. Currently I have an X58 mobo with an i7 920 OC'ed to 3.5 Ghz, 1000 watt PSU and a single GTX 580SC. I was wanting to buy 2 GTX 760s and SLI them. From what I have read I don't think I will be losing much or any with the 760's in my PCI Express 2.0 slots. I was wondering will the 920 at 3.5 bottleneck the sli 760s? Thanks a million!

760s or 670s? You said both. Either way, you will be in good shape. I haven't come across a game yet I couldn't run at 1920x1080 @ max settings with my 2 x GTX 660 SSCs. And I have another machine with 2 x HD 7870s and an i7-875k that runs any game at max settings.

PCIe ver 2.0, even at x8, x8, still has more throughput capability than most cards can use. And the i7-920 is still a powerful CPU. If there's any bottle neck at all, it would be minimal... and then only with CPU intensive games. I'm not sure yet where BF4 falls in the CPU vs GPU battle.

opps! I meant GTX "760"s.

Thanks for answering BTW. I actually changed my mind about SLI..I just ordered a GTX 780SC. Everything I read about Bottle necking gave me a headache LOL. So I will run the GTX 780 with my i7 920 3.5.

It will in battlefield.
I had a 3570k and two 7950's and I had a bottleneck in bf3.
The 760's aren't far off from the 7950.

my i5 2500k OC to 4.3ghz Bottlenecks my HD 7970 OC in crossfire in bf3, all though im going get custom loop to get get a 4.7 or 4.6ghz clock to try and remove as much of bottleneck i can for BF4, i say BF4 will be just as CPU intensive if not more, but with new engine there could be some better optimization for multi threaded CPU's , i know the frostbite 2 engine can use like 8+ cores and use hyper-threading, but coding is not the cleanest , i'm thinking frostbite 3 well i hope that some little optimization is in place, due to fact that druing expo they was using AMD FX CPU OC to 5ghz or something running 4k downscaled to 1080p locked at 60fps, so from that i can say it seems like they cleaned up some of codeing and better utilization of multi threaded /core

Here a tip just incase you didnt know. Since you ordered d 780 n the 580 sc is still a top tier card , why not use d 580 as a dedicated physx card.

 

[bobbyincide666]

Nice! I will do that.

 

[bowzef]

using a GTX 580 as physx card = huge power draw= lowing life of PSU , and its over kill , better of selling it and make some money from it or keep it as a back up for diagnosing any upcoming problems for PCI lans and GPU failures, and monitor failures, just my advice.

+1^
I wouldn't bother with the GTX 580 for PhysX either. PhysX isn't that demanding and the added heat and blocked airflow from the 2nd huge card would be a drawback.

 

[bobbyincide666]

Ok...thanks guys!

Just an update. I got to overclocking my i7 920 again and I now have it at a stable 4.0Ghz at 1.2v. Although it's "old" LOL, I am pretty excited. I am sure this will help increase everything overall with the GTX 780. Thanks again everyone.

Good job. The i7-920 is still a tier 3 processor for gaming: http://www.tomshardware.com/reviews/gaming-cpu-review-overclock,3106-5.html
Overclocked, it is probably in the 2nd tier.
