I bought this card as an emergency replacement for my main card that went belly up. It installed with no problems in Win 7, no extra power 6 pin connector is needed, runs quiet and performs flawlessly. I played Diablo 3 for a month on this card and when my Radeon 7770OC came back from RMA I played Diablo on it. Could not tell the difference between the 2 cards, even though this is supposedly lower rated. I have kept it for a spare for 2 months now and is superflous for me. So, if you have just one monitor this one is all you need.

Maybe not the best card out there, But I had another one by the "other" guys, and it failed in less than 2 years, and they were giving me the run around about fixing or repairing it, so I bought this one. Now the other junk has been replaced, and it's still in the box, cause this one works too good to bother opening the case again.

I am a power surfer though, not a gamer. I use Adobe CS5 Suite and in particular, do a LOT of video editing with Premiere Pro CS5, Dreamweaver, PhotoShop and SoundStage, and this card runs with no glitch. I mean, they are open all at the same time. ;o)

I also use a Visio 31 inch HD TV as a monitor using the HDMI slot.

I had a ~3 year old graphics card that was fairly decent when I bought it, but died on me (capacitors burned up). I didnt feel like buying a whole new system, so I decided to just shop for a new low end card figuring that it would be about the equivalent of what I had before. I settled on this guy based on price and relative specs (including 2x DVI out), and I've been impressed.
- Its quiet! I was used to a loud-ish hum from my system before, but now I don't hear my system at all. The first couple of times I came into my office I was worried that the system had shut down because it was so quiet.
- The gfx performance handily outperforms my old card
- It uses a lot less power than my old card.

Now, you aren't getting a top of the line card, but people shopping for this probably realize this anyway. I'm not a big gamer so this does everything that I need just fine.

This is a great card for the price, i wanted something higher end but was limited by my power supply.

It runs great with Diablo 3, just shy of max settings, runs newest Sim City next to highest settings as well. Ran Battlefield 3 on ultra settings, it wasnt bad, just a pinch of slow down at max so i took it down a notch, still looks great.

i have a Dell XPS, about 3 years old now, so video card was my first update I7 processor of the time, 8 gb ram.

this was the best card i could find being limited by power.

I upgraded from the gt 610 to this gt 640 and it blows it away! It may not be able to play games on high like some of the real expensive ones but its great for this price and runs smooth and cool! Dont listen to the people that say that it cannot run more than two monitors because im running 3, 1 vga monitor and 2 dvi-d monitors and windows 7 instatly recognized them the manufacturer says it can run four but I havent tried four. Great price and great card!!

I bought this lookinhg for an upgrade in my current computer. I expected a card worth $100, instead I found this card to be better then some cards that cost $200-$300. Absolutloy amazong. Plays the newest games on max. The fan is quite, and big:). IF you want a bang for your buck, but this for sure. I also looked at some others for $80-$90, this is 10x better then those, and only a few bucks more. I love it, you would too.

I bought a monitor with 2500x1400 resolution. My previous card kept crashing. this one handles the resolution like a dream. However, I'm not a gamer so I don't know how well it performs under pressure.

doesn't need an extra power source, only PCI express 3.0

Cons:

only two out of the four work at the same time.
