SAPPHIRE 100270SR Radeon HD 4850 X2 2GB 512-bit (256-bit x 2) GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card

Pros: Four monitors on one card!
Quite and responsive

Cons: Requires some software finesse to get all four monitors working.
Hard to come by now.

Other Thoughts: This monster is the center of my system. I used Crysis to test it and it was able to play at maximum capacity while still running other programs.

Manufacturer Response:

We now have the FleX series of graphics cards available which can offer up to 5 monitor outputs depending on your monitors input configuration.

Pros: Does very very well in games, even the newest games (MW3, BF3, GW2, etc.) Cooling is very good, isn't too loud (but that never bothered me), and very long lasting.

Cons: Drivers once in a blue moon can be very annoy, but that's old news. The new drivers are pretty good now.

Pros: Afordable card, 4 monitor ports, easy to install drivers/well updated drivers. Running many of the newer games at Max video settings for beautiful proformance. Using the same money I bought this card for, you will not find anything else come close in proformance.

Cons: Extreamly large card almost a full foot long, I had to cut my case to use it (still worth it). like many of the graphics cards it requires 600watt or better power supply (see specs page)

Other Thoughts: Do not let windows update install drivers in win 7 x64, use newest drivers from ATI website.
Measure your case to see if it will fit.

Pros: Runs 4 monitors off one card. Gaming is not my primary use of this card - it is needing a card for stock trading that runs four, 27" HP monitors @1920x1080. I hoped to go this route and save a PCI slot by using this rather than 2 video cards, and may spare myself any config. issues if the two cards didn't place nice with each other. It functions perfectly. The fans are quiet. Installed in Win7 Ultimate x64 with no issues.

Cons: It's really big. Measure your case carefully before buying one. I didn't have to hack my case, but others have had to modify and that may not be worth it for some. I had to do more experimenting and searching the web than I cared for to get all four ports to run 4 monitors. I didn't come across any documentation from the manufacturer that helped or described what to do to get 4 ports running (disable crossfireX).

Other Thoughts: Here and elsewhere others have complained that it will only support two monitors - not true. Enter Catalyst Control Center -> Graphics -> Crossfire X, and un-check "Enable CrossfireX". Win7 Ultimate x64 set it up with the latest drivers without a problem. Therefore, I did not install the Catalyst Control Center. I've installed the CCC on other machines and never used it. It seems that by default, CrossfireX is enabled on the card whether or not your install the CCC. The only way to disable it, or at least the way I did, was to install CCC, and then uncheck the CrossfireX option. Win7 will then "detect" your additional monitors.

Pros: This card is very Impressive for the cost some say it is noisy but I say it is not any more than that you would get if you have two stand alone cards this card is packing two gpu's and is very impressive for the buck I would recommend I was running duel 8800 gtoc nvidia in sli and was scoring over 9000 in 3d vantage with this card i am ranking over 12000 good jump it

Cons: I have no cons

Pros: Easy install in my full tower, Ran respectively cool considering it is 2 gpus. Finally got to play some Bioshock.

Cons: Well.. this is the second and LAST ATI card I have bought, the first one was a Sapphire and was DOA (Older model though, not this one) .. and this card.. well.. search the net for "VPU RECOVERY ERROR" that about covers it for me.

Other Thoughts: Ran Left 4 Dead 2 - max settings at 60fps constant.. very respectable, however... alot of flickering during loading screens, intermitten "mouse pointer" freezing on screen.. and if you are interested in Secondlife.. don't bother with this card.

Pros: 2 Gpu's , 1600 pipelines , 2 Gigs ram , Sturdy construction , Sexy look. This card even w/o DX11 drivers blows Nvidia clean out of the water without a flinch.

Cons: Big, and can be bit warm.

Other Thoughts: I have owned one of these puppies for just over a year and have not been disappointed. I bought my second one now and have been running quad crossfire, and WOW games play even faster than before and I have no trouble maxing every single in game setting, as well as Catalyst setting. This Card is definitely the best bang for your buck even at $230. I am running with a Phenom 2.8 Ghz quad core on the Asus M4A79 Deluxe board, and find my Grafx even with just one card worked much smoother and more openly(settings wise) with this Mobo, and highly suggest it as well if you plan to go AMD.

Pros: Update to previous review a few days ago. Tried solving the Neverwinter Nights 2 problem, ruling this and that out. I noticed that my pointer in World in conflict was also flickering, but the game ran fine, Bioshock does stutter, but that is a Bioshock problem and new drivers. Nvidia has the same problem. I ruled out the cleaning of old drivers by reinstalling windows. It could also be a windows xp issue, has been noted before in the past with other cards. Seems stable though. In order to get rid of the pointer flickering in World in Conflict, you have to uninstall the drivers if installed them first and then installed the Nvidia board drivers. Reinstall the ATI driver. That seemed to fix it and also confirm that the NVIDIA board and ATI drivers for crossfireX mode do not play well together.

Cons: You really do need an AMD chipset board, probably one that supports crossfireX to make sure there are no compatibility issues. I am currently running a Nvidia 780A SLI chipset board, and while the card does work in crossfire mode on this board in some applications and games like World in Conflict, Age of Empires 3, it seems to have problems in Neverwinter Nights 2 and I am sure it would in other games as well. In order to not have a VPU Driver Recovery while loading Neverwinter Nights 2, I had to disable crossfire and run on one GPU. It ran it perfect that way. Not really a con per say, just more of a heads-up.

Other Thoughts: It would make sense that there could be some compatibility issues with an SLI mobo seeing as how the GPU channels information to and from the CPU through the Northbridge motherboard chipset. So how do you fix this? Well, the only way I see is to create a fushion setup by getting an AMD board with hybrid and/or crossfire X setup to make sure that crossfire mode will not cause any driver issues and make it that much more stable. I can't vouch for intel chips, they may play nice since they don't favor one chip or the other with the x58 series boards. Hope ths helps someone down the road. By the way, I ordered an ASROCK 785g crossfireX board from the egg to fix my small issues.

Pros: -Very fast
-Runs fairly cool
-Cheap

Cons: -Loud
-HUGE (almost a foot, i measured about 11 3/4")

Other Thoughts: For the price it's really an unbeatable card. I got mine for 200$ and at this price it outperforms the GTX285 for a lot cheaper... how can you argue with that?

DX11 is just a gimmick for right now seeing as not too many games are picking it up for this year, so i figured i'd stick with a DX10 card for now since they're cheaper.

If you want monster performance and are sticking close to 200$, this card should be at the top of your list.

Pros: get 20229 3dmark06 stock clocks with amd 945 @ 15 X 260...@3.9
can handle anything full bore 24Xaa . triple buff on open gl....everything - at 1400 900....well some slowdown, get 30fps on COD with EVERYTHING maxed- crysis plays 1400/900 at 8aa with NO slowdown.....this thing eats aa for dinner
noticeably better frame rates than my 4890 XFX non reference....
1600 SP ya
(: sexy looks :)

Cons: overclocking it to 700/1150 has no positive effect on performance.......weird huh ?but true-
non reference....but knew that!
cant play with voltages
rear fan spins slower than front fan....
loud at full speed
DDR 3 is a little pokey at 993

Other Thoughts: overall-++++++
I decided not to RMA because I like...
the best out there now for $$$ because reference 4890s are very hard to find now
will handle high aa better than 4890
peak frame rates might not be as high as a highly overclocked 4890.....I have now had both...
have 2D at 625/993 with traytools and desktop is Very snappy
o/c at 750 and 1150 had a net decrease in FPS with 3dmark 06 and furmark and crisis benchmark.....
If not for the lack of performance increase with overclock would absolutely give 5 eggs...a pretty kick tail card !
fast as is......I like 10 1 drivers the best after trying a bunch of them- I like tray tools over riva tuner.....
Very Respectable card....Seems to like a fast CPU-
my FPS gos up 200 on 3dmard06 with a 100mhz increase on cpu-
when you look at what you are really getting with this sub $250 card it comes up a solid player abit a little long on the tooth
