Win 7 x64 memory question

Upgrading from 4 gigs of PC 8500 to 8 gigs of PC 8500, will I see a performance gain, or will it not make any difference with current software?

If this is the wrong area to post I apologize, I didn't see a memory forum. I also did try a search for the answer with not much luck. Thanks for your reply!
