Been thinking of getting a new graphics card and not sure what to go with currently. My budget would be under $300 or maybe a little more. I currently have a EVGA Nvidia Geforce 550 ti. I like nvidia more than radeon. Wanting to get a single graphics card because of current mobo only has one PCI express 3.0 slot. Would love to move to a mobo that I can SLI but dont have budget currently for that. Any ideas for a powerhouse graphics card that isn't too expensive but will last a while.
