Will 2 GTX 580's be bottlenecked by my CPU? - Page 4

No difference's in this situation.

I have yet to see a core i7 be bottlenecked in these circumstances.

i didnt change my claim, i simply made it more clear and specific to my original intent.
I'm currently smashing my head against the wall. No matter what system you have, no matter how fast you THINK your rig is, there is ALWAYS going to be a bottleneck somewhere. The impact on performance isn't worth it to continually upgrade to find it though An i7 at 4Ghz is crazy powerful, but your confident it CAN'T be bottlenecked? Your too hyped up on your system to admit it has flaws. It is very fast. True. But it has a bottleneck. It's hidden somewhere lol.

i never said it was flawless.

no matter how fast your rig is, their is always one faster. rememeber this.

im confident an i7 at over 4.0GHZ cant be bottlenecked, my reasoning behind this is the fast communication between the CPU NB and GPU's (QPI)

Mixed with insane memory bandwidth and transfer speed's which can keep up with the clock cycle's of an OC'ed i7. making a bottleneck IMPOSSIBLE.

i7 920 at 4GHz shows some BN when paired with HD5870 CF, not only at 1680x1050 but even at 2560x1600. See the gain right up to 4GHz showing no sign of levelling out. BN is not large but it is there.

That isn't proof. That's just you making a statement pulled from nothing. Also, since when are we talking about three GTX 580s? The OP only mentioned two.

Yeah well, it's not like everyone on OCN has a bench ready to go every time you demand proof for something that should be common knowledge.

First you said an i7 can't be bottlenecked at 4.0GHz.
Then you said an i7 can't be bottlenecked at all.
Now you say an i7 can't be bottlenecked at 4.0+Ghz with 3 GTX 580s.

If that isn't changing, I don't know what is. Make up your mind.

What constitutes a basis for 'Common knowledge' thing's u simply believe? and expect other's to know?, it is pulled from looking at benchmark's and research.

you cant just deny what i say and claim it isnt true.

10 GTX 580 won't bottleneck a 980x
post #38 of 77
Answering the question, two 580's will run fine on your sig They'll have plenty of room to breathe.

10 GTX 580's is something that not only cant be done, but hasne been tested.

therfore no way of knowing, and in a impossible theoretical situation, ill bite.

perhaps it would.

try to keep comment's down to earth, and more on the same level as us.

BTW SIGGED!

Depends on the application you're running on it, and your overclock, but it is possible that the i7 with a good overclock could still bottleneck a pair of 580s. But it'll be such a tiny bottleneck it's effectively irrelevant. You will get a significant bottleneck with it running 3 580s, and by significant I mean mathematically or statistically relevant, not necessarily one that affects game play or improved frame rates.
I doubt there is a desktop processor around today that has the sheer power to keep a trio of 16lane PCI-E cards fully busy, unless it's LN2 cooled and hitting 6GHz or more.
