5 out of 5 eggsGreat Card

Pros: Amazing sounding 7.1 Card, full support for windows 8.1
Considering the card is so cheap It makes a huge upgrade over my onboard sound.

Cons: This Con is not for this card but creative itself... Why in the heck is this the only newer card that offers 7.1 ???????

Other Thoughts: For such a cheap price tag, you get some great sound. Just be sure you have a pcie slot open and not blocked by video cards

1 out of 5 eggsDOA (kind of)

Pros: Got it on sale

Cons: The card was some weird form of DOA. I followed the instructions. The first time I tried to turn on my computer afterwards it went to the boot prompt and said "failed to find operating system." not a good sign. So I restarted, this time it booted into windows, and I saw it listed in devices with the "!" sign on it. I assume just because it didn't have any drivers installed yet. So I started installing the drivers from the disc. On the menu where you select where to install, it suddenly froze. Everything except the mouse, I couldn't do anything. had to force restart. Booted and signed in, and within one second everything froze again in the exact same way. So I turned off the computer and un-plugged the card. Windows wanted to do a repair when I booted it up, so I did that. Now it's back to the way things were before I ever started. This was a disaster, and I would be furious if I spent full price on this card.

Other Thoughts: The website for support was a complete disaster. I couldn't find any help on this type of issue.

5 out of 5 eggsRant on Creative Support Site

Pros: Will update this section soon.

Cons: See rant (other thoughts)

Other Thoughts: Potential buyers may wish to know the drivers appear to come as part of a gigantic Creative Software Suite (267MB). Creative: please provide separate driver and application downloads.

The bigger issue is that Creative's support site is EXTREMELY slow. As I write this review the single file is downloading to my PC at an average of 70 KB/s after 30 minutes in the download queue. Meanwhile I did a speed test that shows my download speed as being able to reach 95.84 MB/s (I'm at my workplace which as super-fast internet). You can see why I'm raging. I have better things to do than sit and wait for an hour for a 267MB download.

I will update with user experience after the download finally completes.

5 out of 5 eggsUnderrated home studio gem

Pros: Low latency hi-res hardware based sound processing/recording. Supports true ASIO 2.0 WITH live monitoring. Solid realtime live effects processing and "soundfont" compatible midi synth are in hardware. Heavy tasks are not remotely troubling my CPU. My Xonar cant do this.

The drivers are solid and the card's full functionality is recognized by all of the recording/DAW software I have tried.

Cons: The software bundle is weak. Actually quite lame. If you want a "Karaoke Card" (does anybody really want this?) it might be terrific. Podcasters will also find some benefit to the effects processor and simultaneous input recording/monitoring. The rest is all fluff.

The front panel jacks are shared, not switched. This is a pretty big con that doesnt affect me much since mine is a headphones-only application.

Other Thoughts: This is in many ways an Audigy 4 with a PCIe interface tacked on, so its 10-year old tech. But its good tech, and I don't need a full-on fancy/expensive recordists card. This card was DESIGNED for recording back when, but is not currently marketed that way. Pity.

For gaming, or home theater, I would not pick this. For home recording for the non-novice on a budget, it has been PERFECT; a lot of bang for the buck.

The FX version of this card DOES NOT use the same tried and true EMU chipset. The RX and FX cards aren't remotely related, so cant really be compared for value.

1 out of 5 eggsBEWARE - 3 PORT 7.1 Audio ONLY

Pros: Good looking card, great packaging, pretty solid 5.1 and lower sound.

Cons: Outrageously stupid 3 port 7.1 audio. See Other.

Other Thoughts: Shame on me for not reading the fine fine fine print and then thinking that the pictures in their online manual were of, you know, real cables. Nope. They're not for sale anywhere I can find, they ONLY come with their speakers, and that's it.

Here's the deal -- if you have a Creative speaker/amp then you're in luck - they seem to come with the proprietary cables that are needed to actually hook up 7.1 audio. Problem is that I've got Razor's Tiamat 7.2 Headset. I'm not going to waste my time buying 4 more cables and rigging up some work around for Creative's horrific design choice on this card.
Think about this:
There are TWO Microphone jacks, AND a line in.
Then they went with 2x 4-Poll 3.5mm jacks and 1x 3-Poll 3.5mm jack that handles all 8 speaker channels in a 7.1 setup.
Worst. Design. Ever.
I gave Creative another chance after 5 generations of Audigy thinking it was time to see if they've gotten their game together. I'm fully disappointed.

There won't be a next time.

1 out of 5 eggsNot Impressed

Pros: PCI E x1 card, 24-bit, gold plated I/O, black PCB, headphone amp.

Cons: Fine-tune EAX settings interface is clumsy, no auto mute when plugging in front headphones, amp not so powerful, it kinda performs like my onboard sound...for 60 bucks maaaaan c'moooonn!

Other Thoughts: Consider the Creative Sound Blaster Z instead.

3 out of 5 eggsSB Rx 7.1.... disappointed

Pros: The card performs just as Creative intended it to do. Installed card and loaded the software without a hitch on a home-built dual boot win7 pro 64 and win8.1 pro 64 rig.

Cons: I've been using Creative cards since the SB16 in the mid-late 1990's. Whenever Creative launched a new series, they would support the hardware with improved software capabilities.

Since M$ decided to nuke XP from orbit, I decided to rid all my systems of XP and roll with win7 and win8.1

My Audigy2 live drive and Audigy2 ZS cards are in separate builds and ran tremendously well with Creative software under XP. I was aware that Creative decided to offer Audigy2 support for win7 and thought nothing of it. As it turns out, the driver support for Audigy2 cards under win7 does away with CMSS 2 and replaces it with CMSS 3D. This is an overall downgrade in defined output profiles and sound quality is diminished.

Other Thoughts: I decided to ditch the Audigy's and upgrade to the Rx... thinking that the newest software suite would have CMSS 2 or something that sounded like it. Nope!

It appears that CMSS 2 is gone for good. It's the only output profile that rocked my Z-5500's and my Klipsch 4.1's. CMSS 2 was designed for the big speaker systems as it threw more range to the bottom end and the up-mix for the surrounds sounded more natural with increased fidelity and balance. It appears that the "Z" series has this "3D" as well. I am extremely disappointed with Creative now.

I am forced to re-build a stand alone XP box for my Audigy2's just to use the older drivers that gave an acceptable sound output for my music collection. I'm returning the Rx. Thanks for reading my review/rant.

3 out of 5 eggs7.1 for Creative only

Pros: Great Sound
Easy to Install

Cons: Only 7.1 with Creative Devices!!!

Other Thoughts: I purchased this sound card to plug my Razer Tiamat 7.1's into. They were the only thing Creative had that wasn't sold out, and it was mostly in my price range. I was super excited when it came in. I plugged it in with no hassle, booted up the drivers off the disk, no problems. Plugged everything in like how I thought it should be. And no side channels. Upon inspection, the side channels are "mixed" with the rears, and sub/center channels. Which I guess is how Creative speakers work? I turned it to stereo and spent some time listening to music on 2.1. It sounded great. RMA'd cause I wanted 7.1 though. ASUS D1 incoming soon.

5 out of 5 eggsWindows 8.1 Drivers

Pros: Probably a nice card...Haven't had a chance to find out yet..Always used Sound Blasters in the past, but this one doesnt have the correct drivers for Windows 8.1

Cons: No Windows 8.1 drivers

Other Thoughts: Would be nice if it had Windows 8.1 driver updates somewhere...It should be said that it is not compatible with Windows 8.1 if the drivers are not available..

Pros: Couldn't find out

Cons: The metal backing on the card makes it not seat properly if you do not have enough space between the motherboard and case.
