allan winter :
I have a pny geforce gtx 550 ti already instaled. I can feel heat above the card and i think the fan is running slower. I cant aford much so i'ma have to instal this next one myself. The nvidia site said a 750 ti would be a good bet for me. But my pc repair guy found a 900 model on amazon for around the same price. ...have i lost you yet? my head hurts.
The 700 series is old now. Not obselete but the 900 series improves upon it with cooler temps and more features. The GTX 950 is the way to go especially if you OC it. However, you can pick up the 960 for around the same price so have a look around for that first as it's a more solid purchase. Either way, buy the 950 or 960. But, AMD GPU's are just as good and are usually cheaper. Look for the 370X or 380. Solid GPUs and cheap.
