What’s the latest on this issue?? Advice years ago was to use discrete graphics, but maybe things have changed with the CPU power today.
My system
Asus based i7 2600 k oc to 4.5
I ran it without a graphics card and was fine but a bit twitchy on the asio meter.
Installed a saffire 5450 and it stopped it.
So my humble opinion would be better to use a card
depends on what you need it for. some users have complained of sluggish mixer graphics in Cubase 7. I upgraded my graphics card a year ago for video editing. got an NVidia with cuda gpu. makes my video editing much smoother with hardware fx support. Cubase doesn’t support cuda directly as far as I know (though some plugins do, like nebula). but my Cubase graphics are slick. also, even though the card has a fan (unlike my older one) it is quiet. think it is NVidia gtx460 overclock model. around £130 . ed
