No problems Dec 12 2011

Installed without any issue. No driver issues in Windows or Linux (Ubuntu Oneiric with fglrx). Very quiet - can't hear it over ordinary fan noise. Runs fine without a high-wattage power supply. Like most modern cards, this is rather large, but not unusually so - there were no problems getting it to fit. Runs like a 5770, perhaps slightly faster? Since most games are tracking an older hardware spec, it runs everything I've thrown at it quite nicely.

Overall, a very mature and satisfactory product

It will get the job done, but can always be better Jan. 21 2012
By AnthrSolidSnake - Published on
I wanted to buy a new graphics card that would at least play Skyrim on max (or at least close to max) settings on my new Dell I bought in September. My old graphics card was barely cutting it at all medium settings, and I was rather low on cash, so after browsing on Amazon I came upon this card. There weren't too many reviews that I found on here or on the internet about it, but its specs were well beyond mine so I took a chance. For $120, I couldn't complain if the card couldnt do my expectations, but when I finally got it I was pretty impressed. Installed seamlessly, and overclocked without ANY problems. Skyrim automatically set my graphic settings to all High when I installed the new card, and even after I put all the settings on Max, this card still ran it at an aberage of 40-60 FPS (35 was the lowest, but only breifly). My PC specs arent the greatest, but they are
CPU: AMD Phenom II X4 960T 3.00Ghz (Overclocked at 3.40Ghz)
Graphics: XFX AMD Radeon HD 6770
IT brought my Windows Graphics Card score from a 5.9 to a 7.4, and this card can play any game I own at max settings at at least 35-40 FPS, or high settings at about 50-60FPS (More if V-sync is off)
Great card for the price, and an excellent budget card
As a final note, if you like grpahic designing or video processing, I do that too, and it processes the videos I make in HD format in a fraction of the time my old card did (Original Time: 2-4 Hours New Time: >/= 1Hour
And it doesnt even notice me wathciung videos on Youtube in 1080P

Very good, no surprises May 10 2012

I did have to buy a new power supply (mine was a 250 watt) but the product arrived quickly and installed painlessly. I bought it to run Starcraft 2, and it runs on Ultra (or extreme, I can't remember) it runs on the highest setting without a hiccup.
The card is somewhat large due to the fan assembly (it will take up the room of two cards) but it only needs one slot to plug in to. It also needs a 6 pin power connector from your computer's power supply. It does not come with a converter.

This + Ivy Bridge allows me to run 3 monitors without DisplayPort July 31 2012
By Isaac - Published on
Verified Purchase
I bought this to use in conjunction with an Ivy Bridge processor's integrated graphics so I could run 3 monitors without having to use DisplayPort. It seems that 2 DVI ports on a graphics card is rare, this is one of the only ones I found. I have 1 monitor running through HDMI off the Ivy Bridge's graphics, and the other 2 monitors off the 2 DVI ports on this card, and after a little tweaking in the BIOS etc. it worked like a charm. I don't use it too heavily, no games or anything, but it was simple and painless and works great, so I'm quite happy.

Best for the money May 12 2012

I purchased this item a couple months ago. I will concede that nvidia is probably better. But, for the price this is the card to get. I can play Starcraft II on Ultra and other games. Very solid card. Aside from the lack luster AMD drivers, it's a fantastic product.
