Posted before that I had dropped PD11 for my main work (engineering videos from fixed cameras)
I had bought PD11 as I figured it would be stable, but it was too bloated for my smaller PC. Now I have taken on
a job to convert about 100VHS tapes to std DVD and the tape owners have purchased a suitable PC system for me to work with
as payment (they are saving over $1000 on a quote by doing so)

So now I am using PD11 for the work its really intended to do:
I had a green screen problem with a video, usually a graphics card problem. Fault was that 8GB of my new 16GB ram had failed
and the HD4000 graphics needed just under 2GB of system ram to work, which subtracted from my now 8GB of ram.
Installing a graphics card relieved the RAM overload and fixed that problem.
But before the RAM failure came up, the 3770K HD4000 was doing a good job on editing to standard DVD mpeg2 on the long movies I was testing it with Multi trim a lot faster and much more reliable to use.
No artifacts, but occasional "Director not responding" reports, but waiting for a bit got it back soon enough
The results with my new PC setup make PD11 good to use speed wise, down from an hour to just 3 minutes to produce 1/2 hour videos without SVRT I am now actually looking forwards to using PD11, my previous frustration being that my old platform simply wasn't good enough. ( I do wish that CL would revise their PC platform suitability list)
I am posting this as maybe those thinking of an upgrade to a 3770K could save on an expensive Graphics card if their requirements don't go beyond mpg2 std DVD production and have at least 16GB of system ram under a 64 bit system
The new multi threaded HD4000 on the i7 K series seems a big improvement, but probably still not good enough for Blue Ray production?
I note too that PD11 came up with Multi Sync enabled and some movies produced using SVRT as a default wiith HD4000 being used without having to be selected by me
So far, this new PC is making PD11 much more of a pleasure to use!
