Performance:
Delivered with 512 MB of memory, we get cracking if we push a little (not bad) processor, I have test with Live 5, Battery2 with 1gig kit, and stylus remix is ​​greedy resources.
After that I have put 2 GB of RAM; j've finally been able to appreciate the power of machine.plus no cracking, no sacada when moving windows or changing a patch.
The same test was done on a vaio "high end" and he did not have the shock!
