[plug] Overclocking

[Bob Adamson]

To throw an extra option in here: might I suggest you take a look at a 
program called DraftSight. It's a free (as in beer) autocad replacement made 
by the same people who make solidworks, and works command-for-command like 
autocad (for all but the most recent and peculiar of autocad commands). The 
die-hard autocad guys where I work find it pretty good, and I do too.
I'm unsure of whether it uses multi threading but being newer it's worth a 
shot. It also has native linux ports, but they are targeted at the corporate 
distros.

Indeed, the 3770 will clock up to 3.9Ghz for one core if the other three
are idle. It has some other trickery there to improve single threaded
performance also.

At the moment I'm just using brute force. Lots of volts & up the multiplier.

The appdb comments don't look good. I might give it a go, but my
experience with Wine for almost anything outside of MS Office has always
been hit and miss. Last thing I need is for it to tank on me and destroy
work.

Spot on. Someone suggested I look at one of the VMWare products, so I
might see if any of those handle acceleration any better.
