2 out of 5 eggsWay 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

4 out of 5 eggsAwesome for the price

Pros: Easy install, plays all of today's games, no problems.

Cons: None

Other Thoughts: Upgrading from a 8800 GTX which makes me happy, same size but a lot more powerful.

3 out of 5 eggsGreat 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.

3 out of 5 eggsInconsistent 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.

3 out of 5 eggsCooling 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.

5 out of 5 eggsStill 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.

5 out of 5 eggsGreat 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.

Other Thoughts: Mine was an older version of the diamond 5870 still kicking today. iracing and bad co. 2 being my games of choice right now.

5 out of 5 eggsReliable Brand, Good Price

Pros: This is the third Diamond card I've ever used. I had an X1600 pro from them years ago. I recently just had an HD 3870 from them which I used until I bought this. That card worked great for 3 years, and was well cooled with lots of over clocking headroom. I raised that card from 777mhz to 850mhz on stock cooling. This card keeps up with my high expectations from Diamond. ----- First off, the price is right. The 5870 should cost not much over $380.00 since that was ATI's target price when the 5870 released at the end of 2009. You'll see this card is currently at $420.00 which is reasonable, and is clocked at default factory speeds. You'll see other 5870 brands clocked a mere 50mhz higher costing up to $499.99! The cooling on this card is great, and there is lots of head room for over clocking. I went from 850mhz to 960mhz. The fan is quiet considering the card's power. The heat output is reasonable. The power draw is also excellent, better than Fermi for sure. Diamond is excellent.

Cons: The cons I'm about to list have nothing to do with Diamond, but rather the actual design of the 5870 itself which is credited to ATI, of course. The card is big. It's not behemoth like the Fermi cards from Nvidia, but this card's size is still considerable. The market will have to get used to this, GPU's and graphics cards are simply getting bigger and it looks like this generation is no exception. That being said, their is no other drawbacks to speak of.

Other Thoughts: I've seen complaints of the card have plastic built around the cooling system and having a flimsy fan. Listen, the cooling on this card is great, and there is a lot of head room for over clocking via the Catalyst Control Center or Riva Tuner. As for using plastic, that's not a problem, that's a good thing. Why? Because as long as the cooling is adequate and silent, which it is, adding extra fins to the fan or making an extra fancy aluminum designed heat sink is just "marketing". So if you want over the top cooling, go buy liquid cooled GPU sinks, and if you want some cool looking metallic over lay on the entire card, enjoying spending an extra $100.00 buying from ASUS, XFX, or Sapphire. Unless your card is delivering a factory over clock of at least 100mhz higher than standard clocks, then you're wasting money on what essentially is a $400.00 card. This card delivers high end performance, at a good price, with a reliable life span, and a standard fair warranty.
