It'll work fine. Just uninstall SH3 before you install GWX 3.0 and move your save games elsewhere or create a folder in there purely for your stock saves. My copy of SH3 is one of the later ones where they included everything on the DVD minus the Starforce.
I've run SH3 on a windows 7 laptop with GWX/SHC no probs except video ones. Thats due to a less than adequate GPU though.
