Performance Questions

I'm sure this was discussed in other threads, but those threads are all separate and it's difficult to find the answers.

1. When you change the resolution to be an equivalent of 1900 x 1200 (more space), is there any decrease in performance? Does everything look sharp and gorgeous? Is there lag when scrolling and just going through the system?

2) When doing intensive tasks, specifically cutting hd footage in FCPX, applying filters, effects, or compositing in after effects, and rendering, how much heat is there? compared to previous gen? Is the heat tolerable?

3. How much noise is there when doing intensive tasks described in #2? Is it like a jet engine like the previous MBPs? Is it tolerable?

4. How fast is it? Generally speaking, how fast does it boot up? Launch apps, etc? Does the computer get sluggish or does it handle everything with ease?

Also, most importantly, does Safari feel snappier?

 

Bump

 

Thanks for the reply.

Further bump.

Seriously no one can give a detailed response to my questions?
