Yes, they are both very similar in game-play, graphics and apparently ratings:
Tiger Woods PGA Tour '08 - 7.1
Tiger Woods PGA Tour '07 - 7.0
Here's a snipet which you might find useful.
There is only a 5 month difference in the release of Tiger Wood's PGA Tour 07 and Tiger Wood's PGA Tour 08, and not much has changed. I'd say go for the newer one because it got a higher rating by .1 and they probably fixed some problems from Tiger Wood's PGA Tour 07.Originally Posted by IGN
