The GTX 1070 is a very powerful card and can purchased for ~$370.

The GTX 1060 is also a good card if you're looking to game at 1080p (which most people still are). It can be found for around $200.

the 970 is a good card to play at 1089(admitedly I don't pkay a great variety) but it's fairly enough, specially considering the price

Great, GTX 1070 should be good enough for me. And it is a pascal too.

probably won't ever get this for $300 brand new.

you might be able to find some 2013 Titans for $400.
