Hey all,

I have a desktop computer that has:
Windows XP Home
Intel 2.2 ghz core duo processor
Nvidea graphics card
2 gig RAM
SSD operating system/programs drive (50% full)
7200 rpm data drive (25% full)

I just purchased a new Dell Inspiron laptop that has:
Windows 8
Intel 2.2 ghz quad core
AMD Radeon graphics
8 gig of RAM
5400 rpm hard drive (10% full)

Those are the specs. Here is the question:

I ran the same 3D CNC toolpathing program file on both machines. It took 8 seconds to process on the 2.2 ghz core duo desktop and 4 seconds to run on the new Dell 2.2 ghz quad core laptop.

I had been planning on adding 2 gig more RAM to the desktop PC. However since it already has the SSD hard drive I'm wondering if any excess RAM requirements are using the SSD and subsequently adding 2 gig more RAM wouldn't show significant impact on the 8 second time processing.

I'm also considering replacing the 2.2 ghz core duo Desktop with a machine about equivalent to the new Dell laptop.

So more RAM or new desktop?

Any suggestions on which route to go?

Thanks,
BH

You should invest in buying a new desktop part by part. A new I3 3220 would out preform you mobile quad core significantly and only cost 110$ The platform that your desktop is running ie motherboards chipset DDR2 Ram and so forth have a big role to play aswell as your processor.
