Thanks Ben. One question I have since this old laptop uses what
appears to be a standard Athlon II processor is whether or not I
can swap in a quad core in the same cpu family? Two concerns,
one is a heat concern as this laptop runs pretty hot already
where a quad core may run hotter. Second concern, power consumption.
Is there enough power for an Athlon II 635 quad core processor?
I'm assuming the motherboard has a standard AM3+ socket, does it?
Third question, I know I said there were just two :-) Is running
VirtualBox on top of CentOS for 7 pro going to work on this low end
hardware where Linux does not support hardware acceleration for the
integrated Radeon? Virtualbox 3D support is experimental, so maybe
Virtualbox doesn't support accelerated video anyways. This is a
question of raw processing power, I have enough memory. I prefer
CentOS with Virtualbox if needed for 7 pro, but CentOS does not
support the integrated video card well. I may need a hotter laptop
to run Labview 2010 in a virtual machine. That is, I need a virtual
machine for the Windows version we have unless we decide to go to the
Linux version. If I pitch to my boss, hey, we need a Linux laptop to
run Labview 2017 for Linux. I need to make the case and make it well.
If we buy a Linux laptop, is there any source that will include Labview
2017 OEM installed and ready to go?
