Way too buggy

Pros: I am very disappointed with this product. I paid $400 at the time when this was purchased. It works well for Starcraft II and Civ IV, but other games such as Crysis, Civ V, Sonic Generations, Batman Arkham City, etc. will lock crash with a black screen or a black screen with grey lines. I have tried everything to remedy this and nothing has fixed it. I'm switching over to NVIDIA.

Cons: buggy

Great Card but...

Pros: Really great graphic card that vastly improves your gaming experience. Pretty much every game I tried with it was able to be run at max settings with little to no slowdown whatsoever.

Cons: ...but the card I purchased lasted only a week before it quit working.

Other Thoughts: Other then that big con, I was really happy with the card in the short time I had it. I have since ordered a new card of the same type hoping that it lasts this time.

Inconsistent Build Quality

Pros: Standard Radeon HD 5870 implementation. Good performance, reasonable power consumption, pretty good cooling solution. Seems to work fine with the generic ATI drivers.

Cons: First card had intermittent issues: white "snow" speckles during games, screen corruption upon wakeup, messed up textures, etc. Because these problems only showed up some of the time, I spent weeks trying different drivers, configurations, and power supplies before I finally gave up and RMA'd the card. Replacement card seems to be working fine so far. RMA cost me $53 though because I had to forfeit the $40 MIR (couldn't get a replacement in time to meet the 30 day submission deadline) plus $13 to mail the card back to NewEgg.

Other Thoughts: Don't buy this card based on the MIR because you might not actually get to collect it.

Cooling not as pictured.

Pros: It's a reasonable card, similar to others.

Cons: I got 2 cards, one was as pictured, with the squirrel-cage fan and front-to-back air-flow. The other has an IMHO fairly traditional single fan configuration which vents half inside the case half outside. The boxes for them both are identical, unfortunately.

Other Thoughts: These cards put off enough heat that I'm relying on them venting out the back.

Still Lovin It, Now in Crossfire.

Pros: -Able to max out most games with 60FPS or better
-Runs cool at Idle 32-40c
-Temps maxing out games 52-70c
-Price keeps dropping
-Overclocked with ease

Cons: -In crossfire, ATI Catalyst will not let you adjust fan settings for 2nd card

Other Thoughts: I bought this 1 year ago to replace a 4870X2. It runs faster and cooler than the 4870X2 and got better frame rates in mostly all my games. I finally got around to buying a 2nd one for crossfire last week after the price dropped. Crossfire me is great on my ASUS Rampage Extreme using Dual 16X lanes. My friend has 2 6870's and to be honest, the 5870's are a better choice.

Im debating moving to Sandy Bridge and 1155 Mobo because my 775 socket just ain't cutting it anymore. But until more 1155 Mobo's make Dual 16X PCI/E available, I will wait. From what Ive read, the 5870 in crossfire performs poorly at 8X/8X PCI/E.

Until then I am happy with the performance and would highly recommend a pair of these in crossfire for those running Dual 16X mobos.

Great Card

Pros: I have had this card for over a year now and couldn't be happier with it. I have never had any issues with it (other than the occasional ATI driver mishap, which is usually fixed with newer releases) and it performs beautifully.

Cons: None

Other Thoughts: This card overclocks very well and I have never had any heating issues.

I am still debating on whether or not to go for a 6970 as this card works so well for me, its almost worth getting another of these than a different card.

Also, this card outperforms the 6950 in almost every benchmark.
