Would a 2500K bottleneck a 690?

Seeing quite a few posts on here recently of lads stating that they had to go to an I7 to make the most of a 600 / 700 series dual card set up. Im currently running the aforementioned hardware, and was wondering if I was getting the most out of the card.

The only game it struggles in, at all to be fair, is Black Flag. Jittery FPS maxed out even with PhysX off.

Who has had experience of upgrading their 2500K CPU and seeing an improvement in FPS? CPU's never seem to drop in price, so would it be dead money?

Thanks.
 
As said, OC as much as you can.

I went from 2500K to 2600K and the only games that I really noticed a difference in were BF4 and Crysis 3. Most other games should be fine.
 
Don't get drawn into the must need an i7 crew... :)

Black flag is a crap port so runs crappy anyway.

I upgraded from a 4.6Ghz 2500k to a 4.6Ghz 4770k and hardly see any ingame difference. Even when I had dual 780's other than benchmarks I did not see a massive or any improvement even in BF4 at 1440p.
 
Bottlenecking is something that is evident in some games but for the majority, it won't show or be a game killer. I wouldn't worry about it unless games are at unplayable frames.

+1

Using a single GTX 690 I just ran my 3960x @4.5 with 4 cores and HT off (2500k mode), then with 4 cores and HT on (2600k mode) and finally with 6 cores and HT on (3960X mode). I ran the Dirt Showdown bench @1080p max settings.

The scores were all within a couple of fps of each other with the best average actually run when the CPU was running in 2500k mode.


Having said that though the Dirt Showdown bench does bottleneck my 290Xs when switching from 6 cores to 4.

Using more than 3 cards it probably will. Running 2 cards and I doubt they'll be any difference at 1080p.
 
It is a shame at times that my Titans are under water, as it would be good to test in my Wife's 2500K comp and see just how much a bottleneck can be and what the lows/averages difference is.

It is something I would like to see tested.

In the Dirt 3 benchmark.

No difference in Fps between my 3960 and a 4770k with a pair of 780's both running identical clocks.
 
The chip is overclocked to 4.5, any more than that and it spazzes out randomly during games even when prime is stable. I think I'll hold out for the time being, as the only real need I've got for the extra threads is encoding.

Thanks for all the replies.

Try turning the cores and threads off in the bios and your CPU will perform near enough the same as a 2500k, they are both the same architecture. I did this some time ago when someone wanted to know how a Titan would perform on an i3 CPU and got it almost spot on.
 
I personally found min fps to be quite low in certain games with dual 670's and a 3570k at 4.5ghz, switching to an i7 3770k even at a lower clock speed resulted in better minimum fps, higher gpu use and lower cpu use. Less stuttering too.

Could do but would prefer to run it on Z68 for a real comparison.
