Pros: A card that can run 6 monitors is awesome, if done right...
Cons: I read in a review for an older model of this same card, that greater than 3 monitors at once requires an ACTIVE adapter, and that the adapters the card comes with are PASSIVE, meaning you have to buy ACTIVE adapters. These ones (at the link) are recommended: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100017680%2050001180%2040003048&IsNodeId=1&SubCategory=3048&Manufactory=1180&SpeTabStoreType=131
Summary: Whatever you do, don't over clock it. This is not meant for that. I tried it, with my asus bios template setting because I'm lazy, and the card got loud. Extremely loud, as in a constant buzzing noise like a bumble bee. Ever since I toned it down I haven't had a single problem again.
Pros: This is a great card for gaming, it can play most games (my monitor's resolution ATM is 1280x1024, so I don't know how it'll fair at 1080p) from high to ultra settings. It's a very good little card, and it will surprise you. It'll games like DayZ or Chivalry (Chivalry's breaking point would be a 64 player server at custom settings which will pull you down to around 30 fps). Some games require a bit of playing around with the graphics settings to find that perfect bala...
Cons: It gets hot. The hottest it's ever gotten is about 55C. Over the summer, I've decided to take some precautions so that it doesn't get too hot. I'll normally put my computer to sleep regularly, and I'll leave the ceiling fan on whenever I play games. This has proven to me that you can keep it cool, because after these precautions we're taken it now stays, on average, around 47C.
Summary: We are running monitors with DisplayPort inputs, so we haven't had to deal with the whole adapter issue. Eyefinity 6 is a great out-of-the-box solution for Windows. Two stars because it is great when it does work.
Pros: When working properly, these are great cards - I have its predecessor (HD 6870) driving a 6-screen visualization wall at 5884x2216 after bezel compensation. With an IR touch bezel, folks love it.
Cons: I've received two cards in a row with problems on port 6, making them unusable in our application. All warranty requests must go directly through Visiontek, even though the card was defective on arrival. They only have refurbished cards available, as the production run has already finished for this card. The telephone support guys have been helpful, but they are not the same folks as the online support that have to issue RMA's. Two e-mails in two weeks, not a single r...
Pros: Very easy set up on Windows 7. I'm a noob so it was a little tricky getting the monitor set up right. Using this card to run 6 Dell UltraSharp U2312HM for work. I don't know how to do all the SLI and Crossfire business, so it was simple setting it up with the 6 mini display port outlets. If you have the money and need a 6 monitor set up, look no further.
Summary: My primary purpose of 6 monitors is for work and not gaming, so not sure what gaming performance would be like. I want one key and one mouse to rule all the monitors, so I can have different remote connections in each window
Pros: Card works. I was concerned about the reviews and how they range, but the card works. It requires the ACTIVE Mini Display Port to DVI adapter for all 6 monitors to work. 2 are included in the box, so I had to order 4 more. You cannot use the PASSIVE Display Port to DVI which are the other 4 in box. I tried several configures but would not work, unless I used the Active HDI-D. Also one monitor didn't work using DVI connection, so my assumption is that it was an older s...
Cons: I could only get 3 monitors to work using the passive cables. Perhaps someone with more time to study configuration could get it to work and monkey around with the drivers.
Summary: I used two of these to run a 12 screen video wall for work (12 x 1080p). It was a huge pain to setup and is very glitchy. Hardware specs: i7 haswell, ASUS z87, 750w PSU, SSD. Pros: Runs cool Supports 6 monitors (with a lot of work) Cons: Displayport (more info below) Glitchy when used with 6 monitors Extra Info: To get it to work, I attached 4 monitors in DP 1.2 mode, then two monitors were daisy chained in DP 1.1 mode. I did this for both cards.
Summary: Was incredibly easy to setup eyefinity on for a 3x1 monitor setup 1920x1080p. Has held u; to near constant use for a couple months with no issues so far. Will upgrade to 6 : 3x2 monitor setup soon.
Don't buy this if you actually need 6 displays or live outside the US

Summary: The product appears to have a design defect where under load one of the display outputs goes blank leaving 5 working displays. Visiontek refused to honour their warranty citing an unstated policy to require any returns to come from/to a US address. This is not stated ANYWHERE in their web site or public documentation. In a global economy where they sell directly and through other vendors to customers anywhere in the world this is petty and naive.
Summary: Very happy with this. If you get cerified Active adapters for dvi it works with all six monitors as long as you have the amd drivers in. Don't be lazy and just use what windows 8 has generics for for AMD. This is by far not a generic card. And on my second computer with this im able to run 6x of these http://www.amazon.com/gp/product/B00EMB4KVI/ref=cm_cr_ryp_prd_ttl_sol_2 n with mini dp to dp cables i got from monoprice (sorry amazon.
