PowerColor Radeon HD 6870 x2 2GB GDDR5 PCI Express 2.1 x16 CrossFireX Support Video Card with Eyefinity AX6870X2 2GBD5-2DHG

Pros: One of the fastest single card solutions available. When the HYDRALogix chip actually works, this is a huge feature allowing you to crossfire/sli nearly any combo. Runs reasonably cool. Others have had luck overclocking and keeping temps under 80c at load. Absolutely screams through Crysis 2 and BF3 at maxed settings! Has issues with others however (see below)

Cons: May have to RMA (hope not) but no matter what I do, I cannot get HYDRALogix to install. Constantly get error "HYDRA driver installation is aborted. No HYDRA hardware was found". I cannot get this card to run with any other card until HYDRA is working and that was the main selling point for me. I am also getting bad artifacts in RAGE where it looks like a bad overclock yet running at stock speeds and have all current drivers on clean install. No aftermarket cooling solutions (at the moment) and difficult to run liquid cooling loop. Several "universal" waterblocks will not fit. Heavy card and sags in the PCIE slot. Currently being supported by my H2O pump. Measure your case before purchasing/installing....very long card at a foot (maybe even more, didn't measure as I have plenty of room) in length.

Overall Review: I am coming off a 4890x2 setup and although I know this card is smoking fast (when working properly) vs other current gen cards, I've found a renewed respect for the mighty 4890 in crossfire. There isn't that much of a difference aside from DX11 support (with regards to gaming and overall benchmark scores at least): 3DMark Vantage - P23k (vs 20k with 4890x2) Unigine @ 1920x1200 - 2236 (vs 2030 w/4890x2)

Pros: Two GPU's on one card. 13 Phase Power. As reviews have stated, both cores are stable at 965 Mhz at stock voltage. Memory is stable at 1200 Mhz(4800Mhz eff.) Trixx and afterburner works fine with this card. Both cores will run at 1Ghz with a bump in core voltage and proper case ventilation. Quality card. Excellent cooling solution.

Cons: None

Overall Review: Would love another in Xfire. Running four cores would be awsome. Price is keeping me away. One is more than enough in most all applications. Make sure you operate this card in a 16X lane. Running two 6870 cores in a 8X lane will bottle neck.

Pros: low power consumption,runscool

Cons: i replace my 6950 for this and on mafia 2 im getting 55 fps average my 6950 got 70fps. micro getting stutter on almost every game. i meat all the requirements my build is amd t1100 6c0re 850w powersupply 8 gigs ddr3 1600

Overall Review: im 3 days past being able too return it too newegg guess ill send it back too powercolor and review again

Pros: This card for the price has unbelievable performance in most games. I did see some micro-stutter during Saints Row the Third, but overall performance in every other game seemed great.

Cons: After installing the card I personally had several issues arise. At times my computer would freeze booting into windows, freeze on bios splash screen, crash during games, and no video output or loss of output during use.

Overall Review: In theory this card is great, but for me I had nothing but problems getting my system to work properly and keeping it working when it did work. I attempted troubleshooting the issue by disconnecting devices, updating bios, reinstalled OS, and even changed out power supplys but nothing kept the issues from happening. I'm very happy with Newegg for taking care of it for me and giving me a refund to purchase a different card.

Pros: Runs WOW and Homefront so far without a hitch on the highest possible settings. im hoping it will do the same with battlefield 3 when it comes out.

Cons: HUGE! well really long. pan on having 2 video cards side by side. install disc was a bit confusing due to the screen being jumbled up.

Overall Review: make sure to have a big case, a big power supply. im running a corsair 700watt

Pros: You can crossfire this card with another 6870 or another 6870x2 and have very high frame rates with little to no microstuttering as long as the game or application supports crossfire. The card runs relatively cool for the amount of power it draws and the amount of space it has. Under full load with the fan turned up to 80%, GPU1 is at 58 C and GPU2 is at 71 C. Not bad.

Cons: Depending on the game, sometimes it won't work as intended (aka no crossfire support for some games). When there is no crossfire support, it will only use the GPU power of one card, but that's not Powercolor's fault. It's loud at full speed and somewhat loud at idle. What can you expect though? It's two 6870s on one board. I also received a broken card the first time I ordered it and received a working one when I RMA'd it. See my previous review to see what happened with the first one. It also does not overclock too high on stock voltage. I overclocked each GPU by 15 MHz and had some minor artifacting when running them at full load.

Overall Review: Great for bit coin mining! Also: If you're having trouble running Skyrim with the newest drivers, it's because you have to select the bioshock profile in the Catalyst drivers. It will then work in crossfire mode.

Pros: 2 GPU crossfired on one card Heat piped heat sinks and large area fins Temps are good under heavy load, typical at idle Considering there's 2 GPUS on one card the fan noise is pretty good

Cons: A long card and heavy heat sinks makes the card sag downward towards the end. I don't like seeing a card bending, maybe could have put something to make it more rigid. Using the power cables at the end to prop it up so not that big of a deal.

Overall Review: 3 GPU crossfire with XFX 6870 2GB memory for total of 4GB, runs smooth and no problems with compatibility between 2 different brands. GPU above the XFX card runs 10C higher than GPU at the front with open space. Having more open space for the fans really helps it cool better but can't do anything about that.

Pros: This card has great performance for the price. It has similar performance to more expensive cards. I have two PowerColor 6870x2's installed and haven't had any problems. I'm using a Corsair HX1050 1050W power supply and don't have any stabililty issues when running FurMark.

Cons: The card requires crossfire support. This could cause issues if you are playing the latest PC games.

Overall Review: When switching crossfire modes it's easiest to uninstall the AMD driver, install the second card, and re-install the AMD driver. The correct crossfire mode will be selected automatically when the driver is installed. I didn't have an option to select CFx4 when I added the card without re-installing the driver.
