Summary: The best video card your money can buy. You can read some complains about this card over the internet abou framepacing issues. Thats all old news. All issues have been fixed in driver updates and this card is the fastest one in the market. Better than gtx titan, gtx 780 ti and r9 series.
Buyer beware of your monitor connectors before installing

Summary: The video card has done very well by me. I run four DVI monitors from my computer. I had two Nvidia video cards pushing the monitors, but the system would lock up periodically or a single monitor would click out (even after switching it with a different monitor.) So I purchased this video card to replace them. Installation was easy and simple and even freed up a couple of slots on the motherboard. However, once it was installed. I purchased Display Port to DVI 6' cables.
Summary: So as soon as I received the Sapphire HD 7990, I was quite surprised by its size right out of the box. The build on it is very strong and when you hold it in your hands, you can almost feel the power it will perform on games. I was very excited to receive it and test it out on all my games. I installed the video card and installed the latest AMD drivers ( CCC 13.9 at the time). Everything was installed pretty smoothly.
Summary: A few things to keep in mind about this card from my experiences, this is definitely an enthusiasts card (obviously) it is going to take some tweaking so it does not burn itself up like my first card did. First off make sure you install the 13.11 beta drivers, and enable frame pacing under the game settings, the card is dirt terrible if you use 13.9.
Summary: This is overall a great buy, for an enthusiast gamer, or someone looking for multidisplay pwnage. I can play Skyrim, Crysis, and many other games on full spec, no problems. Other Thoughts: Card is huge! Make sure your case has adaquate space. Requires 2x 8PIN PCI Power/Card will draw 400 watts/ish under full load. Make sure you have a beefy power supply to handle the load.
Summary: This is one of the best cards on the market and its not even the most expensive! When you consider that you get 3 games from AMD and another 8 Free games from Sapphire It is very good value. Mine doesn't have any coil whine. It runs a little warm but nothing to be concerned about. The fans move lots of air and it doesn't make much noise at all, the noise you hear is air rather than the distracting kind of fan noise other cards might make.
Summary: Tried to run this next to another card and the fans broke off of it. Waiting on my liquid cooling supplement so I can run games on high without this thing overheating and shutting off my computer. Also, this doesn't throttle itself like other video cards, the temp will just go through the roof and shut your machine down (at least on windows 7 that is).
