Thanks in advance for any help. Here's the deal: I have an XFX double dissipation radeon r9 290, and am looking to upgrade. Processor is an i5- 4690, and I have 16 gb of 1600mhz ram. Motherboard is an MSI z97 gaming 5. I want to know, purely performance wise, what is the best. Msi/Nvidia gtx 970, or r9 390. Also, if someone could compare that to my current r9 290 that would be wonderful. I don't care about price, power consumption, or noise, though comments about power consumption would be noted.Thanks guys!
