Interesting suggestion.  Well, KInfocenter tells me that the 3D accelerator 
is by Intel: "4 Series Chipset Integrated Graphics Controller".  The driver 
is by Tungsten Graphics and the renderer is "Mesa DRI Intel Q45/Q43 GEM 
20100330 Development [hmm...] x86/MMX/SSE2".  I run the OS from one WD HDD 
on SATA.  Processor is Intel E8400.
