Hi,

I've started overclocking my PC with an i7 2600K to 44x and noticed the stability of the system was not good anymore. The performance of PD11 increased a lot but I got spontanious hangs in PD11, Cubase 7 and my RME fireface (driver) somehow also started hanging. So I decreased to 40x OC and want to check the coming week if this stabilizes the system.

So what I noticed is that the basic editing experience in PD11 is not relying very much on the graphics card but mostly on the CPU. OC-ing helps a lot to increase the editing/preview speed.
By setting the OC to 40x the performance has decreased somewhat so I'm now considering again to upgrade my Radeon HD 5450 to the fastest silent card or an active one which is not too pricey.

The fastest silent card I can find ATM is the Radeon HD 7750. I'm also considering the GTX 650 Ti which is active.
The reason I'd prefer a passive card is that I'm also recording in the same room which is probably going to get less likely to work when I add 35-50dB of noise when adding an active card.

So can someone please share their experiences with different graphics cards and how they influence the editing speed/behaviour in the PD11 timeline (editor). I don't mind if the rendering takes a little while longer since it's mostly done in 5-10 min anyway.

I prefer setting the preview in PD11 to Full HD/Realtime so that's the setting I'd like to use as a starting point. At what level will a graphics card stop adding speed to the previewing in PD11?

Thanks for your replies!

Cheers,

Harry
