I think you will find that what you buy is what you live with.
From the quick specs you can get it using the integrated Grafic process built into the CPU (ie for SB cpu probably the HD3000, or HD4000 that comes with the IB CPU) or you can buy it with a 540 V w/512 Megs of dedicated VRAM This i possibly a alternative to SB/IB CPUs that do NOT have a iGPU (SEE MY not at the Bottm on 540v performance - Would be foolish to stick a 540V on a system with a HD4000).
From quick specs:
"ATI Mobility Radeon HD 540v discrete graphics with 512 MB dedicated video memory
or integrated Intel HD Graphics"
The 540V is NOT a gaming gpu, it located close to the BOTTOM of Class 4 for which is MUCH lower than a HD4000 - OUCH
