Overclock it? I bit the bullet this morning and it appears to be working just fine with titan's "kernel-power" - run a search for this or alternatively jakimans overclocking guide and see if that helps. Bear in mind this is only if you want to void your warranty. I did this because I was getting frustrated with sound hangs and loops, slow camera image processing speed, slow loading of apps and jerky transitions. Everything appears to be working faster and smoother now. For the time being.

I don't care about my warranty personally.
