Both have onboard graphics, but both should run SH3 - more or less laggy with harbour or convoy cpu/graphics load.
However - your No.2 will have a better performance.

Do you have access to them? Tell your story and ask for a SH3 demo (
) - or something actual 3D.
Displays are 1366x768 (-)(but ok for SH3), and anti-glare (+).
Keyboards are full size - including NumPad (+)
8GB DDR3 RAM (+) (not sure if your spec is true for 511!?)
1TB HDs (well - not necessary in your case) (+)
Peripheral equipment ~ average but ok
No.1 ~ £350.00
No.2 ~ £380.00
Not sure if they will run XP if necessary - as MS has no interest in supporting drivers for new hardware. But SH3 should work with Win 8.x anyway.
