Commitment to space for a reasonable price

= 3 modules installed 24GB more (with the 3 4GB modules already installed, I have 36GB).
W7-64 reacts perfectly, ability to run all the necessary apps simultaneously without slowdown.
For example Firefox with 20 tabs open, thunderbird, multiple residents utilities, adobe reader, viewer photo, Photoshop with more than 50 pictures 8MB one, Excel, Word, etc ... without any perceived inconvenience! I've never been able to use more than 16GB ...
Starting even faster W7.
I recommend this purchase to those who are a bit patient: within about 2 months.
