Hello, I was thinking about buying the R9 280X, since it is on sale.
My specs: CPU - FX-6300
Memory - 2x 4gb DDR3
Current GPU - Radeon 77XX
PSU - Seasonic SS-620GM2
I've read about R9 280 supply, and even though the official sites say min. is 750W, many were recommending 550W high-quality supply. How is it with R9 280X?
Thanks for replies!
