is there any point to synthetic benchmarks ?

i see all these programs designed to push hardware such as 3d mark /sisoft sandra etc and i think is there any point to them ?  sure its nice to see what the hard ware could be capable off but in the end you need REAL world programs to test what the hardware can do programs/games that people actually use day in day out

i dont think anyone would buy a graphics card to run 3dmark what do i care if it runs test 2 at 60fps ...no it will be to play the witcher 2 or skyrim for example

Also i suspect companys will tailor there drivers to do better in a synthetic benchmark then a real world program

All i ask is pc hardware review sites please just do real world stuff
