If you want to go AMD, then the Asus R9 290X DirectCU II is an absolute monster card. PC Per reviewed it and the custom cooler completely and totally solves the throttling problem - this baby just stays at a solid 1GHz GPU clock the whole way through and really shows what this GPU can do. Of course, it runs really quiet, too. At a mere $20 premium over the stock card, a 50MHz stock overclock, almost the same performance and all at $130 less, so much cheaper than a 780 Ti, getting it is a no-brainer and will lower 780 Ti prices for sure now. I reckon we could even see a price war between them. Bring it on!
