Right now, I'm cross-firing AMD Sapphire 7790 HD cards and I'm wondering if that will be good enough to run most games in 2014 on high to ultra settings with little to no framerate issues (for example, I plan on getting the Witcher 3, which I REALLY want to play on some high-end settings). Will this get me through this year and if not, are there any cheap to moderately expensive ($400 per card max) I can get?
