Random question but i've got a 2700K at 4.8Ghz, will this be O.K for the higher end cards like if I want to XFire/SLI the current gen, top end cards? I'm just wondering how long my 2700K will last me for basically.
Ok just tried the same map with the 2700K @ 4.5ghz and the minimum according to fraps was 72fps. Both GPU's again at %99...
Both on the same map with lots going on. The 2700k holds 2fps over the 2500K, with both CPU's it felt perfectly smooth and tbh if I did not know which was which I would not have been able to tell them apart.
Now I'm going to disable my 2nd GPU and try the I7 with a single GPU and then re-install my I5 and do the same.
All good fun...

How does the i7 2700k run BF3 at stock clocks?

As BF3 benefits from HT probably pretty well compared to a game which doesn't.

I'm just wondering.
What are the real world gaming benefits of overclocking? (Your modern i5/i7 CPU that is not GPU)
By modern I mean either Sandy or Ivy.
I can see the point of overclocking the 'last generation i5 and i7'

Overclocking an i5 will help considerably in BF3 and other games.
An i7 I'm not so sure if it will all that much (if any) as the threads help to eliminate the b/neck...

4 screws on a H100i it takes a couple of mins tops...
No hyperthreading on the 2500k just four cores.

BF3 on a single 7950 is horrid..It's no longer silky smooth.
Fine for me and I'm pretty sensitive to low FPS. It's not 680 smooth but not far off it.

sehr interessant
What resolution?
1080p 120Hz....
With the single 7950 @ 1000/1600 I can see quite a bit of juddering and general slowdown. Fraps is saying the min is around 42fps.
Soldato
Is 120 Hz not the problem then?
Soldato
Ah - I run 150 MHz faster so unsurprisingly don't experience the same.
Refresh rate has nothing to do with frame rate. The perceived slow downs are because it's dropping to ~40 FPS.
No. Not THAT much difference between 1080 and 1200. In fact the difference is negligible.

I normally run two and tbh have not found any need to go higher. Even with the cards at stock 800/1250 everything runs perfect. I clock them to 1000/1600 and on stock volts they run cool and quite.
