But most of your heat is coming from the GPU. You would be better served to buy an AMD 480 and have much better performance with much less heat going into your room. At one time I was running an 8350 @ 4.5 ghz along with x2-6970s and was seeing over 700 watts being pulled from the wall. Now I am running an 8370 @ 5 ghz @ 1.512 vcore and a power hungry 290X and am seeing power draws of around 530 watts from the wall. The 480 performs as well as the 290X and is much much more energy efficient.
Get a 480 now and enjoy the cooler room and then make your decision on where to go next.

gotta be careful with statements like this
HD 6870 has a TDP of about 151
RX 480 has a TDP of about 150
their coolers are designed to dissipate similar amounts of energy, but obviously the RX 480 is doing a considerable better job than HD 6870 though they are using roughly the same amount of energy
Contrast that to something like R9 290x with a TDP of 290w.. lol, RX 480 performs better then the 290x but not to such a large degree as compared to the HD 6870, but it's out putting considerably less energy then the 290x.
like R9 290x is at 85c
RX 480 is at 85c
the only thing that means is the coolers are keeping it within a thermal envelope, because both coolers are rated considerably different for the GPU's they need to cool, the energy they consume and output are different compared to RX 480 and HD 6870 which are rated similarly
