Is the Zotac GTX 970 compatible with MSI B85 G43 motherboard?
I don't know more about your questions. But when i playing games, i use a auto-detective software to helps me download and update my drivers. It will auto recommend me what drivers me need to update, it is very easy and helpful for me.
The GTX 970 would work in PCIe 2.0x16 slots and up, which the motherboard has a PCIe 3.0x16 slot and would work fine. As Phil suggest, you would need a sufficient power supply, which 400-500 watts would be recommended (I suggest a quality 500 watt power supply that is at least Bronze rated). Another thing to look at is the dimensions of the card and check to see if it would fit inside the computer case. Some cards are longer, wider, or taller than others, and many people do not take the size of the card and the available space in the case into consideration.
It will work just fine in that motherboard, install the card to the first/top PCIe 3.0 x16 slot for the best performance. Also make sure you have a power supply capable of powering it and the rest of the components in the system. A quality 350watt psu would handle the entire system assuming a single graphics card, along with an i7 (highest power draw cpu available for that motherboard), a couple hard drives, memory, and cooling fans. A 400-450watt psu would be recommended.
