1 out of 5 eggsWish this was an XFX card. . . AVOID! Last PowerColor I'll own!

Pros: If it works, it's fine . . .

Cons: Card just stopped working. . . No display!

PC boots, fans spin, num lock key responds and I can boot with other cards. . This one just up and died and it's not even my main PC that gets used daily.

Other Thoughts: Card wasn't the best card I've owned; however, it was a gift, so I can't complain about the cost and when it worked for the short time it did, it was ok. . . From what I've seen, it's an overpriced paperweight with cheap plastic and no real consumer service backing the poor product! PowerColor appears to be out to get their money and not support their consumers. I guess they don't want long term customers and that's why they make cheap product that you're completely out of luck if you don't have a receipt. They should take notes from XFX. I suppose that there being almost the same amount of people that give this 1 star as 5 stars should be a strong warning about buying these products!


It's the first and last PowerColor card I'll ever own and I'm glad it was a gift and I didn't pay for it! I normally use XFX or ASUS. I have a dozen or so video cards, older and newer ones, and this is the first card I've had an issue with the RMA process. I can't even submit without a receipt! What a joke. . . I never got the receipt when it was gifted to me. . . AMAZING! XFX RMA'd two of my 3 Alpha Dog Series 8800GT's without the receipt and being 4 years old! I had submitted claims just to see and XFX was more than happy to help and expedited shipping. . on 4 year old cards!!!

Anyways, with poor service like this. . . I don't see PowerColor ever being a serious contender. . They're the Ford Pinto of graphics cards. . .You buy, drive for a couple months and they explode!

1 out of 5 eggsNever Again

Pros: They look neat

Cons: I bought 2 of these for a crossfire rig a year ago. I have had nothing but problems with these. Random crashes, BSOD's and app crashes. I finally figured out that one card sucks more than the other, so I just yanked it out, and now it only crashes every once in a while with just one card.
These things get really hot, even without overclocking. I was pushing over 80c with stock settings on BF4 (only one card because it would crash after 10-60 seconds with crossfire up)

Other Thoughts: I'll never buy power color again, utter garbage. Save yourself the time and trouble and just flush your money down the toilet.

4 out of 5 eggsbought 2 both work great

Pros: Works fine, cooling is fine, quit,

Cons: Not as fast as i need ( I stream so its a little slow for me )
when im not streaming though its fine 200+fps on league of legends with a i5 2500k stock clocked has a little trouble with call of duty black ops on med settings so thats a little sad

Other Thoughts: I bought 2 of these cards one for my brother and one for me both are still working to this day and doing just fine, like i said the only reason im getting rid of mine is becuase i my computer for hard and needy programs and i just need a better gpu all in all though a great card

3 out of 5 eggsDecent

Pros: Good card with low power. Handles my casual gaming requirements.

Cons: Not quiet at stock settings. If you're looking for a quite card out of the box, this isn't it.

I had issues with the video "shaking" with this card since I got it. No artifacts like you might expect when overheating. And the tempurature didn't need to be warm for it to happen. I exchanged email with their support and sent them some videos of the issue. They were polite but no resolution was ever decided on. It wasn't terrible for the most part so I just dealt with it. Just recently installed Win8 and didn't even think about it but I haven't seen it happen since. So might have be some weird driver issue or hardware conflict or something.

Other Thoughts: So yeah, the fan control on this card is just stupid. I believe the default fan speed when idle is 40%. It's not anywhere near quiet at this level. Using Fanspeed, I have it off during normal operations and the temps are fine. If I push it with furmark, the fan gets up to right around 40% and the temps are within a reasonable range. So the factory default minimum is close to what it should need to be max really. (Note that I left the fan speed at stock settings for a test and still had my issues with the shaking output.)

The card overall is fine. I really was hoping for a GoGreen HD7770. But it doesn't seem that PowerColor is making one of those. So I decided to try this one. Given the issues, I would be tempting to go with Sapphire as I've never had any issues with them.

5 out of 5 eggsGreat Video Card

Pros: This card has outdone the games I want to play, I have had no overheating issues so far, and I'm overall having a good time. This is my first time owning a gaming PC, (before, I was using laptop for gaming) and to be honest, this card is the icing on the cakes. Ventilation out of the PCI-E slot is a smart way to keep this card cool, and overall, I'm just having a super time.

Cons: None.

Other Thoughts: I don't know why people are complaining about the reference design. This is just a great card in general.

1 out of 5 eggsSupport?

Pros: Easy to remove from the system

Cons: I have two paperweights that are in the way

Other Thoughts: The manufacturer responded in the typical condesension it only makes it worse.
On a brand new system twin cards, BSOD on basic programs that are normally stable, I replaced both with twin Nvidia 660's guess what? Now my new system is stable, and can run max on everything just like a I7 3770k should. My son put these cards in another system and this AM I found them back in my office, When I asked What gives, his only reply was GARFF!!! JUNK AVOID LIKE THE COOTIES

Manufacturer Response:

1 out of 5 eggsBSODs

Pros: None

Cons: Caused random blue screens.
Cards ran over 70C even at 100% fan speed on load, idles around 50C (78F/50%RH environment, housed in a Corsair Obsidian 650D).
RMA'd the cards and had to pay re-stock fee, shipping fee, and a fee for a pickup of the box.
If you're considering on buying these and putting them in Crossfire because they're cheap, well I hope you get cards that actually pass quality control.
I'm sticking with the manufacturers I know and trust.

Manufacturer Response:

The temperature you've listed is actually perfectly fine under full load. The maximum temperature of the card is 105C before the card will go into fail-safe mode and either throttle down or shut the computer off. Though it may be unfavorable, anything of 95C or lower isn't anything to really be concerned about in regards to temperature.

If you are having issues with the cards not working though, please feel free to contact me at in order for me to assist you directly.

Thank you,
