Well I purchased the ASUS GTX780 which is supposed to be one of the top GTX780 cards and also runs cool from what the reviews are saying. My 7970 has been running close to 90c on load and so heats up my room pretty fast. During the testing of the 780 I will re-seat the cooler on the 7970 and see if that helps it's temps and then if the GTX780 does not cut it for Rift I will return it and suck it up with my hopefully cooler 7970.
