Hi all, I got my tax return and I'm thinking of spending it on a 7990. I really crave 60fps in all my games and I feel as though the 7990 can get the job done. It also comes with an amazing bundle of games and it can bitcoin and litecoin mine really well. I was thinking of getting an 850 watt power supply and move this power supply to a second rig that would probably get the 7950 I have now. However, if I can tri fire a 7990 and 7950, I'd keep both cards in this rig. Can I do that and should I buy a 7990 if my goal is 60fps at maxed out or near maxed out graphics? My monitor is 1440p btw. Thanks in advance.
