So I'm buying a new video card to use instead of the integrated one on my computer and I have come down to 2 choices.
first
ZOTAC GeForce GTX 750 Ti LP ZT 70606

second
ZOTAC GeForce GTX 750Ti ZT 70605

The difference between them is that the 605 has Direct X 11.2 (feature level 11_0) while the 606 Direct X 12 (feature level 11_0)
I tried looking on the internet for information about the 2 types of Direct X
but not much that are helpful in explaining it. So can someone please explain to me which video card is right for me. I'm using a windows 7 OS and the manufacturer said both of these will work for Windows 7

Here is a link to help on the comparions

If you need more information let me know

-update- please understand that in my situation and by the specs of my computer I'm limited on my options to these 2 cards, which I can get new for very cheap right now. This the best I can get right now.

Thanks for all the answers, it turns out the Zotac model cards aren't distributed at the store anymore and they began stocking the EVGA 750Ti instead so Thank you to turkey3_scratch for the input.
