Okay, I'm selling my 7770 and upgrading to either the 6850 or 7790.
----
The 6850 rose up in the pool of choices due to my overclocking hobby. And it appears that so far a 7790 will pretty much prevent me any serious overclocking.
I have read everywhere that the 7790 has a locked voltage and a very low CCC limit on all non-reference cards, witch is not aided by software such as Trixx and Afterburner. With the two cards being nearly the same price, why not the 6850? Can someone prove me wrong..

6850 , 7790

If those were my choices im taking the 7790 I have been looking at benchies for it and it competes with the 6950/70. Its overall newer tech and for the same price 7790 all day. I'm at work and on my phone or I would find those benchmarks for you. Think it was anandtech or tom's that had them
I have crossfire 6870's and when I saw that 7790 beat out the 6950/70 I was in shock.

This doesn't seem to agree.

If I can overclock the memory to at least 1200mhz, then the 6850 would do a lot more than trade blows with a 7790.
Pixel rates are almost 30 percent higher than that of a 7790.

Can I see those? On the benches I have seen it's more on the 6870 level, sometimes morse, sometimes getting a bit close to the 7850 level. Note that it shouldn't overtake the 69xx level on performance, because the 7850 usually matches the 6950/70.

Whoa. You should never judge a graphics card's performance based upon number of shaders, TMUs and pixel rates. The 7790 is a different architecture, so it will be more efficient.

Well for this particular comparison, I can judge as the leap in architecture performance was good and all, but it wasn't that grand.

Well then...
7790 competes closely to the 6870, which I would assume makes it even with a 6850, and considering the wasted tdp of getting a 6850(120+W) it makes 7790 a good choice.
----
But about that overclocking...
While a competing 7790 is existent, It probably will fall behind compared to a 6850 at nearly the same clock speed, and the 7790 wont have the headroom to really leave the 6850 behind like some state.

Not real sure on the performance of the 7790, but that 128-bit GDDR-5 would make me shy away from it.

I suggest spending the extra $20 for a 7850 1GB and just go with that. It also comes with two extra games vs. just one if that makes any difference to you.

HD 6950 ~$130-150 used. or HD 7850 ~$170-190 with games.

Would never pay $150 for HD 7790.

Not a dedicated gamer, but the deal sounds nice.
That is also another advantage to getting an x800 Card of the x7 cards, the extra memory bandwidth.
Would it be safe to conclude that a 6850 at 1010/1200 would demolish the 7790?

Because all benchmarks represent a 6850 clocked at a mere and modest 775 mhz.
