So I have a decent rig with a 750W power supply but when I built it at Christmas I re-used my 7950. With the new games like witcher 3 or watch dogs will my graphic card be able to run these games a high performance or will I need to upgrade them? I have heard from other sources that I should cross-fire 7950's for better performance but I have heard bad things like microstuddering or instability. Would cross-firing be worth the hassle or should I just upgrade. I only have about 500$ set aside but I also am going to use that to purchase new games this year so I want to go with a cheaper option but if getting a new card like a r9 290 would be a major upgrade I would be willing to get it
