I'm kind of like-minded on that. Not having the onboard GPU isn't something I'm really losing sleep over (though I guess if I thought about it long enough, it would seem wasteful). I wasn't planning on using the new build for any video work, so I don't think I'll miss the hardware transcoding. SSD caching -- seems to me at first glance that, while you're probably going to get a performance boost from it, it's going to come at the expense of additional writes to -- e.g. shortened lifespan of -- the SSD (?).
