Should i trade my xbox 360 falcon version in for a jasper?

OK, Got my PS3 and just got my xbox 360 in the mail today. Dell was selling the 60 gig pro holiday bundle with endwar for $268. So i ordered it. I had read about how to see which motherboard you have (Falcon/Jasper) and mine ended up being the Falcon. My question is this, should I see if I can swap it out at Bestbuy or another retailer in order to try to get the Jasper? Is the sound that much of a difference? Is the power consumption that big of a change? It is sitting in its box right now but figured i would try to get advice first. Oh also, is the jasper just for the arcades? I read an article saying that they had 256 megs on board and i remember hearing they needed to do that for NXE. What are the failure rates for the Falcons?
