Is the AMD R9 M470X GPU even better than a Nvidia GTX 860m?
I'm looking at some sites and it's more or less similar. still 2GB VRAM though! That base model just has a slightly better CPU over R1 and cost a lot more, it's awful deal. It's not polaris unlike the model number suggests, it's a rebadge.
R2 starts at 800, don't look at the base model ever. And that's too expensive.
You definitely can build something far more powerful yourself at that price point with RX480 coming soon. This wasn't the case when R1 launched and can be had for 400 controller included which would be 50 bucks by itself.
