guys, I will say it again: the best thing, with the biggest influence about preventing microstutters is optimizing your OS & drivers.
the best improvement is made by having at least 8GB of RAM and getting rid of system's page file! you will need, of course, lots of RAM to do that. I had 8 in the beginning, and from time to time I was still receiving the System will be out of memory warning message now and then, but I was still keeping my Chrome with like 40 tans opened all the time in the background. After I went for 16 GB, I had no other warnings at all, no matter how many other programs I would keep running in the background
install the latest DirectX 9.0c
install the latest drivers
turn off all the firewalls/antiviruses programs you have
turn off all the not needed programs/processes/services running
have fun
