I bought it yesterday and downloaded all the plugs and updates. Took several hours. I got up this morning and installed. I installed X3 and just the new features. Then I went ahead and did the updates.
It's running so good it scares me! Latency is so much better! The only problems I have had so far has been the Console Emulator noise on mono track, which everyone is aware of at this point. Turned off the 64 bit precision engine and VOILA! Quiet as a mouse.
This feels like the best version of the X series, Hands Down!
Barring it having any major problems with your system I say GET IT NOW! I'm sure that they will iron out the Console Emulator problem by the next update.
I am thoroughly impressed with the way that Cake is handling this launch! Thumbs Up For The Bakers!
