You could get 2 7970s for $600. From what I have seen the 290x is right around the Titan, if not a little slower... BUT the drivers are immature, where as the Titan has been out for a while. I don't think you should pay that much for a card, UNLESS you are swimming in money. If you are congrats buy all the stuff you'd like! Xfire 7970s beat the Titan and the 290x, the frame pacing is much better if I remember correctly and wouldn't scare me off. Just my .02. What resolution are you playing at if you don't mind me asking?
I don't want to deal with Xfire ever again! I sold my two 7950s because of that. I bought a 1440p monitor.
It's probably a typo but when I Google R9 290x a sponsored link shows up on the side from Newegg with the price of the R9 290x at $9999.99. Wouldn't that be something? xD
Anyway, from what I understand the GTX 780 TI will basically be a hair below the Titan in performance, which should be exactly on par with the 290x. It might be more expensive than the 290x due to the premium construction of the chassis, better power efficiency, stronger architecture, and stable drivers. Way down the road when the prices drop you may even consider SLI the GTX 780 or 780 TI. And if you do you won't have to worry about frame latency and other anomalous issues that typically are not present with nVidia cards.
I also had a pretty shitty experience with 3 different Radeon architectures on 2 different series of cards in CF. So if you ask me I'm nvidia all the way. And I can't imagine the GTX 780 holding it's release value after the r9 290x hits the scene. They'd have to drop the price at least 5 - 10% to stay competitive. Otherwise the 290x is just too good of a deal.
