4 out of 5 eggsPretty solid

Pros: Can run most games on mid to high settings
Great if your just looking to play casualy

Cons: Fan started to slow down had to replace it

Other Thoughts: After a couple months the fan started to slow down and make a grinding noise. I had to replace the heat sink but that wasn't a big expense. It still holds up a year and a half later and can run pretty much everything you can throw at it if you don't mind playing on a lower graphic setting.

1 out of 5 eggsIt was a great card, until it caught FIRE!

Pros: Affordable, quiet, and efficient. It was capable of playing BF3 and Crysis 2 at 1920x1080 at around 50FPS. I really enjoyed fire..

Cons: Like I said in my title, It literally caught fire. I was playing Civilization V at 1920X1080 at max settings, and it was running like a champ, then suddenly my computer just shut down. I went to go turn it back on and saw a bright orange glow, I look down into my case and I see fire. at the connection to where the power supply connects to the card the transistor right next to it ignited into a jet of flame, I quickly ripped my case apart, and removed the card.

Luckily the rest of my hardware was OK, but the card was toast. I have sent it back to HIS for RMA and I am awaiting replacement.

Other Thoughts: As this card is now discontinued I would have suggested for anyone reading this not to purchase it. I would not like this to happen to them as it did to me.

1 out of 5 eggsBAD FAN

Pros: Excellent video card very powerful for the price

Cons: Fan started making noise within 3 months, failed in less than 1 year. Can't ship out card for warranted replacement and they won't send out a fan.

5 out of 5 eggsGreat Card

Pros: I got this card on sale for about $90 and it came with Dirt 3. I have pushed this card hard with BF3, Diablo 3, LoL and Skyrim and it has been flawless. I think most of the negative reviews are from people just expecting to slap a new card in old hardware and expect that to work. If you are upgrading parts from a 7 year old machine... you may need to build a new one, just saying! I have never experienced any of the issues anyone has said about locking up their computer (seems like a driver issue to me) Just keep it updated and you will have no problem. As for fan noise, I wear headphones if I am gaming, so I don't notice anything, this is not meant to be a super quiet media center card. It's usually only $100... so take it for what it is. I would recommend this to anyone, and am getting a second to crossfire.

Cons: It runs a little warm so I recommend a case with good air flow.
The card is also thick so make sure you have a decent size case as well.

Other Thoughts: If you are looking for a mid ranged budget gaming card, this will do fine, and later you can crossfire it for better performance. If you are a person that really doesn't know a lot about new hardware, and drivers, and basically things that are important.... don't bash the card, do some research or get someone that knows what they are doing to help you.

3 out of 5 eggsCheap Fan!

Pros: Works great. I have it driving a 24" 1920x1200 monitor on DisplayPort and two 20" 1600x1200 monitors on the DVI ports. Lots of VMWare, some basic Photoshop, seems t handle it all just fine. Not a big gamer so can't comment.

Cons: Six months in and the fan died. Card cranks to 100° C and then my PC stops dead in its tracks. Doing some Googling and finding bad fans to be common. Vendor site does not offer any convenient way to RMA or even just purchase a new fan. Very disappointed.

1 out of 5 eggs

Pros: None to my knowledge so far.

Cons: A friend and I each bought this graphics card with our Christmas money, and graduation money. For my friend, it stopped after a month of use. (Crashing, etc.) For me, however, it never worked. I amongst many others have absolutely double-checked everything as to make sure it was hooked up correctly. I have a 1050 Watt power supply, so power is not an issue. This graphics card is poorly made, and I would never recommend this to anyone. I am very disappointed that i wasted over 100 dollars on this card. While others on here at least enjoyed their card for a day, mine never worked. I cant send this card back either, for I had originally thought that the card would not work due to lack of power from my old 450 watt power supply. By the time i got the money for the 1050 watt supply, I was out of time to send this card back. Not happy.

4 out of 5 eggsgreat card!

Pros: Great card for the price, produces awesome viuals for gameplay!

Cons: The only real issue I am having issues with bottlenecking.. but getting a new processor will hlp that.

Other Thoughts: I had been looking around for a new, good graphics card, and consulted my friend on which and what kind to get. He reccomended a 6770 over any 7000. (within the price range)

1 out of 5 eggsWaste of Money

Pros: Looks Very pretty
Runs smoothly ... when it runs

Cons: - Failed in a week of normal use
- Unreliable
- Cheap

Other Thoughts: I bought this as part of a larger upgrade for my computer. It came in along side with the new SSD drive and 8GB of extra ram to install into my i7.

I took it for a spin and it worked well for the first week. I was in the middle of playing a game and my computer locks up. First attempt to turn it back on fails with a beeping code. After looking it up I find my graphics card has failed.

I sent it back to newegg to only get rejected because the proof of purchase is on the sleeve it comes with (lets put important information on useless material, that's a great idea). No support from vender, in fact HIS only lists a Hong Kong phone number.
