6870 vs 6850

I would say 6850 cause you can overclock it more.

The 6850 is the better bang for the buck.
For a powersupply, I would go for

for a power supply that's cheaper in price.

for a video card i personally have a 6950 but i do believe that the 6970 will in the end be a better value due to the following:

6970 has a fully enabled processor vs the 6950. I know you can flash the 6950 to a 6970 bios but their is a reason they placed the 8 pin power attachment on the 6970.

the drivers will get very good in the next 6 weeks, going from 10.10 to 10.12 gave a 4% increase in fps.

His talking about 68xx, not 69xx series.

Me, personally - 6870, not just coz i have one, but also for the extra shaders   And its just sooo cheap right now.

The 6850 can easily overclock to 6870 performance. If you don't overclock, the 6870 is still a good card. The 6850 would be the better bang for the buck.

i agree with that and if you can find one for $200 that seems to be the best price right now
