PHOTOSHOP CC

i've been wandering through the forums for about an hour now and none gave a simple answer.
.
.
.
1.) Is there a way to buy photoshop CC on full?
.
.
2.) Will I be able to buy it by itself without any other programs included like bundles or so?
.
.
3.) due to these questions I'm more willing to buy the CS6 version than the new. will there be massive complications in my computer if i do so?
