I have a matrox duel VGA video card in this computer now. If all else
fails, as long as I can find a driver, I could use that.

I an thinking about getting a new desktop, as well as the netbook.
I will be running mostly ham radio programs (dxlabs, N1MM logger, Multipsk,
Airmail) but will also be the general all around house computer. I do some
picture editing (nothing intense), music, and of course the internet. Not
much into games, other than the older command and conquor games.
How much performance gain will I see with the Intel® Core™ 2 Duo E7500

only way to know for sure is to build both systems, and then measure their

Its important to balance the CPU with sufficient RAM. My impression is that
some users are beginning to bump against the 3GB RAM limit imposed by 32-bit
versions of Windows. If you're planning to use this system for awhile, you
might consider installing Windows 64, even if you start with 2GB of RAM; if
you go this route, be sure that

Will the Integrated Intel® GMA x4500 Graphics do 2 monitors, with the

the ATI Radeon HD 4350 512MB? Unless I get new monitors also, I would be
