I was looking for a cheap GPU to get my brother for his comp, and I found a Sapphire 6970 for just $109. I know it uses 250 watts and that it is 2 generations behind as far as AMD cards go.
Considering that for the same price of a R7 250X which has 640 Stream Processors and the 6970 has 1536 Stream Processors. I would like to know if it would be worth buying the older card that uses more power?
Yes, the older card will be worth it (if gaming that is). I have an HD6950 that can hold its own and isn't all that much slower than a GTX770, so an HD6970 should be pretty close to a GTX770.
