This is 2 ½ years I use this computer almost daily, he did not drop me, always starts first turn, the latest system update and programs.
It allows me to make beautiful recording sessions run unabated, I worked on an album almost entirely (mixing and mastering), combined with a good sound card (01X + i88X then Focusrite Saffire Pro 40), it n ' is never at fault!
No worries spots on the screen.
I bought it with the largest configuration (except the hard disk 1TB instead of 2TB) for quiet a long time and not have to change too frequently, it is not yet passed, I think I have 2 - 3 years before me!
A very good buy!
