titan, gtx 780 bottleneck questions

MANOFKRYPTONAK · Apr 25, 2013

I have an i7 2600 non k, asus p8p67 deluxe 16gb 1600 ram. 64gb crucial m4 ssd, and a 500gb wd hdd and a 680. I am considering selling the 680 and going to SLI 780 for a future proof build. I might consider a single titan.

But would my i7 2600 non k and pci-e 2.0 bottle neck sli 780s?

my cpu runs at 4.2 over clock, is that good enough.

Or do I need a new build? ivy-e 6 core with pci-e and sli 780s?

You'll be fine.

You certainly don't need a 6 core processor either.

If you want to do an upgrade for the CPU in the future just go with a haswell i5 -k version.

Moving to PCI-E 3.0 with very high end cards gains you a few percent. Not enough to be concerned with. Your 2600 overclocked via Turbo to 4.2Ghz is also very good. It's plenty for a Titan and probably dual GTX 780s. Going with a k model processor and overclocking to 4.5-4.8Ghz would also gain you a few percent.

Ivy Bridge gains you about 8% clock for clock over Sandy and Haswell should gain another roughly 10% to that. So upgrading to Haswell would gain you between 15-20% clock for clock over what you have now. The PCI-E 3.0 would add roughly a 5-10% graphics boost.

So should you upgrade everything? It's up to your budget and if you are concerned with squeezing every percent of performance out of your games. There would be an upgrade with Haswell the only question is it enough of one to justify the cost. Only you can answer that.

I agree with anort3

Yeah... Don't worry about 6 cores... 8 more powerful cores are coming from both sides in 2014

lol and you should be just fine with two 780s and an i7. for now LOL! nothing is future proof my man! GDDR6, 22nm and stacked RAM is all coming out next year! or is supposed to. Lol. But hey, It'll last you a while for sure!

So do you guys think it would be more beneficial to wait until 2014/2015 until there is a bigger leap in tech? How much do you think my rig would sell for?

General rule of thumb is to add the price of the parts new and subtract 30% for being used. I suppose you are in Alaska based on your sig and that may change things since at least from what I understand everything is more expensive up there.

2014 should be Broadwell and 2015 Skylake. Broadwell will be a refresh of Haswell like Ivy was to Sandy and Skylake will be a new architecture like Haswell will be.
