Question 1

Does this card have: 2048 Stream Processors?

Accepted Answer

Yes it does! Information below comes straight from AMD website:

Up to 925MHz Engine Clock
3GB GDDR5 Memory
1375MHz Memory Clock (5.5Gbps GDDR5)
264GB/s memory bandwidth (maximum)
3.79 TFLOPS Single Precision compute power  
GCN Architecture
32 compute units (2048 Stream Processors)
128 Texture Units
128 Z/Stencil ROP Units
32 Color ROP Units
Dual Geometry Engines
Dual Asynchronous Compute Engines (ACE)

Question 2

Need help. New install on the Gigabyte FFX UD7. I'm getting fans working but no video, and that's plugged into the number one PCI express X16 slot. Any ideas? The processor and power supply work, motherboard powers on, all fans on... not sure why no video output/ DVI out to DVI cable, tried both slots for DVI connector and multiple mobo slots.  The XFX HD 1050W PSU has 1 - 12 Volt rail, so the power for PCI Express is one cable with 8pin and 6 pin , separated. Should I use just the one cable? or two? I'm at a loss right now. want it to work and need it to work.
Thanks, Joe K

Hi Joe, have you tried a different card on that lane? If a different one works but that one doesn't I would say you got a bad card and to rma it. If the other card does not work then you may have a pcie problem. I would update all drivers and reseat the card then try a different card. Good luck buddy, hope it works for you.

Question 3

right now i have the http://www.newegg.com/Product/Product.aspx?Item=N82E16814162075 how good of an upgrade will this card be

Accepted Answer

The 7970 is a pretty good GPU, but the cooler on XFX's version is not that great. She runs pretty warm with stock clocks, and forget about overclocking. Even a mild overclock will run the card at temps I'm not really comfortable with. Pick a different manufacturer. I built a system with MSI's 7970 (TwinFrozr3 cooler) and it performed MUCH better.

Really, since you already have an nVIDIA card, you should consider the gtx 680. Its a great gpu (and what I'm currently running). From what I've heard though, the 770 is on par with it, and slightly cheaper (or maybe it was better for the same price. I'd look into that more).

Question 4

Is DDR5 the same as GDDR5?

Accepted Answer

You can visit Tom's Hardware (great site for tech info) and view the answer supplied by an expert.  Basically he states that GDDR5 is primarily tuned for graphics cards where DDR5 is for system use.  My interpretation is that both will deliver the speed inherent with the DDR5 format. i.e. very fast!

If you Google DDR5 vs. GDDR5 it will show up in search results. Look at the link for Tom's Hardware.  Hope this helps you.

Question 5

Can I run crossfire with this card alongside this one? http://www.newegg.com/Product/Product.aspx?Item=N82E16814121560

Accepted Answer

Yes. You can run this card in X-Fire with any 7950, 7970, or R9-280x.

I am actually running this card in X-Fire with a reference 7970.  The specs for the two cards you are talking about are the exact same.

You shouldn't have any issues and can actually run them both at 1050 MHz on the GPU and 1450 MHz on ram without any issues. Anything past those overclocks are still with in reason. I have found my cards run without issue at those speeds which put them in line with the 7970 Ghz edition at full boost.

I have successfully overclocked at higher rates but these cards are beast and with two there really isn't a good reason to produce the extra heat.

Question 6

Does this card have two dual-link dvi outputs, or one dual-link and one single link?  The specs on newegg say the latter; visual inspection suggests the former, and I have reasons to need a single card with two dual-link dvi outputs.  They seem to be hard to find.

Accepted Answer

Excellent card....the double fans keeps it very clean and very cool
as far as the duel DVI links 1 dual and 1 single

Question 7

Will it work with my mother board p67A-GD55 b3?

Accepted Answer

The short answer is yes, assuming your case has room: that motherboard has a PCIe slot the card will work in.  However, you may not want to.  The motherboard is only PCIe 2.0, where the card is 3.0, so the board will technically not be able to communicate with the system as fast as it would on a motherboard that supports 3.0.  Beyond that, the most important consideration is not just the slot type, but the power supply you're using.  Modern GPUs take a ton of power, so make sure you have a supply that -exceeds- what the card needs safely (since you also need to power everything else!).  Hope this helps!

Question 8

Are these new smaller pcb and cooler voltage locked? Anyone overclocking? what were your results?

How are idle and load temps?

Noise?

Accepted Answer

Are these new smaller pcb and cooler voltage locked?

- This card is the Larger PCB, Same length as my ATX Motherboard

Anyone overclocking? 
 -Yes

what were your results?
-Currently Running 1050 CoreClock 24/7

How are idle and load temps? 
-Around 75c Under 100% load over the corse of 6 hours of gaming, around 35c while Idle

Noise?
-Coming from a Gtx 480 This Card is MUCH quieter, The Fans dont ramp up as much either, great card
