HD 6870 is better than HD5850 esp when you CF it.
I would recommend waiting for 69xx because they might bring price cuts. If you don't want to wait, HD6870 @ 14k.

Ishu its a 95watt cpu and runs much cooler and has less tdp. These facts also has to be considered. 760 runs at a much lesser stock speed and owing to its lower tdp and heat levels can touch 4ghz in air.
Any of the thubans can touch...... no wait , attain stabilty at 4GHz with stock cooler. Get a Aftermarket air cooler and you are set.
Now if we compare 760 and 1090t @ 4ghz intel will come up with trumps in clock per clock execution. Even tomshardware recommends this cpu at its pricepoint.
Anyone can recommend anything. Toms is generally biased towards Intel.
TMPenc. I have used that and its slow.
Phenom II X6 1100T BE processor review
Look at the video encoding bench. And Cinebench
Benchmark Results: Applications : AMD Phenom II X6 1100T Review: The New Six-Core Flagship
Look at the handbrake & mainconcept bench
Also look at Autodesk 3ds max
The power draw is significantly high in thubans and go off the roof when overclocked. Check this.
According to that link
1075T @ 3.75 takes 61 extra watts on load but 1 less watt on idle(Than i7 750 @ 3.75). Now how long do you intend to keep you CPU on load?? It will probably be on full load only during rendering, where it will be much faster.
CPUs are nearly idle most of the time. Like when browsing etc.
