Building my new rig and want to know which route to go down. I've heard that the R9 290x scales fairly well when crossfired but I'm also acutely aware of the issues that come along with having more than one GPU. So, this begs the question: do I shuck out the extra $100 for two R9 290x, deal with the high heat and high power consumption or go with the tried-n-true strength of the Titan? Feel free to pontificate all you want. I want someone to make me lean one way or another rather resolutely.
