Not having ever bought a graphics card in my life, my eyes glaze over when I see requirements expressed as “NVIDIA GTX 970 / AMD R9 290 equiv. or greater” (and ditto for CPUs such as “Intel i7-4700 equivalent or greater”). Product codes don’t sort in any order for me. I’ve tried looking at them but just I can’t say if an NVIDIA GTX 970 is better than an Intel HD Graphics 6000.
Since I’m a Mac guy, having these expressed as specific model and years makes more sense.
