I think you may be confused, PS has always created raster graphics and for quite some time they have also allowed creation of vector graphics.
If you are using version 6, you are using a 5 1/2 year old product ( see [en.wikipedia.org...] ). The newest version (CS2, actually 9.0) has been out for a year.
The improvements over version 6.0 are way to numerous to mention. I'm not sure what the upgrade cost would be, but if you use it professionally, any price including the full pop retail price is worth it.
