Although i agree with most stuff lol I do have to say I'm the kind of person that wants the best and I have about 10 thousand to spend right now which I'd rather keep in my pocket because in three-four years when I move out and build my own living room based on a home theatre system I'm going to want the NEWEST and TOP equipment ladies and gentleman thats just how it goes for me!
The minute the ring goes on her finger, her priorities will change. Your $10K will instantly get sucked into all the house hold items (which imo is a good thing).
Hell, if you open a 529 with that $10K you'll be LIGHT years ahead of people (for your future children's college needs)
