Mine runs fine, even had it overclocked for a while but the air was melting my side panel window.

And that actually happened. The crimsom drivers' bugs killed a lot of cards. It fried the VRAM of my 7870.

Do you have evidence for this? Just asking.
RedRaider (07:32 PM, December 12, 2014)
If that is the case, why is it that my wife is using an ATI Radeon 850XT fine in 2014? Sorry, if you had a bad experience, that in no way means your claim is the rule or common and my wife's computer disproves your greatly over generalized claim. I think it's user error.
RedRaider (07:25 PM, December 12, 2014)
yeah, this site is a joke. The 7870 beat their pet nvidia card in the vast majority of benchmarks and all they can say is something about it's power consumption? I guess performance doesn't mean anything here.

All AMD GPUs are seeing an increase in price due to supply and demand. People are buying them like crazy due to bitcoin mining.

7870ghz went from $150 to $250

The only problem is the 7870 will artifact 2-3 years later when AMD adjusts the catalyst drivers to make them artifact, They do this now with the 5000 series and older, to trick you into thinking you need a new card, But if you get the 660 2-3 years later you will be fine.
Greg (02:38 PM, January 7, 2014)
Only problem is amd will adjust the catalyst drivers 2-3 years from now to make the 7000 series cards artifact like they do withh all older cards to trick you into thinking it went bad, But if you buy the 660 2-3 years later it will be perfect.

The 7870 is not only a great deal cheaper, it matches and outperforms the 660ti and has exceptional overclocking abilities. It's a no-brainer. The 7870ghz, even though sporting the Pitcairn core, is the real gem of the 7-series. Best bang for the buck out there.
