I've been looking to buy a 750ti for my pc, which is a Gateway DX4870-UB318, but I've been having trouble with finding out if it's compatible with the card. I've been trying to research, and so far it seems like the card is compatible, but I just need to make sure. Also, if it is compatible, is there anything else I need to connect the card to my pc? I need to know ASAP!
