R9 280X Crossfire Benchmarks????

[Criticalacc]

Ive been looking for a while, and I know the card is still relatively new, but has no one really tried crossfiring two R9 280Xs??? Does anyone know of any sites that have? NOTE: DO NOT refer me to a 280X 7970 crossfire benchmark PLEASE. I understand they are relatively the same, but still. I want two R9 280X benchmarks.

They are just a 7970 GHz, meaning, you can use 7970 GHz CF benchmarks.

It's just going to be around double the single card (280x 20fps, cf 280x 40fps). Not much you need to know.

Well, I would look up 7970 benchmarks, but I honestly just want to be precise about what I'm buying. I'm debating whether I should buy a 770 or 280x and I'm going to SLI the 770 at some point if I get it, so I want the exact numbers of each brand so I can make an accurate decision.

I will try to remember to post here for you a little later today. Been messing around with clock speeds on each card first. Crossfire in a short while. Right off the bat, the msi 280x is slower than my ghz card when I put the clocks the same. However the 280x clocks higher on stock voltage.
To be honest, the 770 will likely be higher in SLI. But if you are going to pay $900 just buy 3 280x's lol.

I researched both the 770 and the 280x extensively before my decision to go with 2 280x's. (originally had 2x 570's, and then 2x 660 ti's.) I too am hoping to find 280x crossfire benchmarks. Based on my research, the 770 and the 280x should perform to almost the same level depending on the game, as some games suit different cards better. I chose the 280x over the 770 because of the extra vram and $100 less per card, and I chose the Asus DCUii top 280x over the 7970 because the cooler is a double slot, allowing for crossfire capability in just about any midtower, whereas all the asus 7970's were 2.5 slots.

My cards are scheduled to arrive monday, once installed I will try to remember to post back here my findings on BF3, and later BF4. It is my plan to review the 280x extensively in BF4 so I might be able to advise people going forward. Either way both cards will be great depending on the games you wish to play.

I have ALWAYS been an nVidia fanboy, and I am really looking forward to working with these two radeons. I'm sure this comment didn't help one bit!

I am in sales, and when a client of mine faces a tough decision, I always say that a wrong choice really can't be made, through research and perhaps a little trial and error, the right solution will present itself to you.

My vote = R9 280X crossfire, hopefully FTW!

I have two 280x Matrix. I could send you some firestrike scores if i had 3DMark but im not going to pay for something that ill only use once. If you want, i could send you some heaven scores which i dont understand but you probably would.

if you honestly just want to be precise, then know that an R9-280X is PRECISELY an HD 7970. Every single review site has stated that they are exactly the same card. The R9-280X doesn't even have TrueAudio to set it apart so the performance is the same. It even crossfires correctly with the HD 7970. I am running 2 Gigabyte GV-R797OC-3GD's in Crossfire so I can tell you my benchmarks with an FX-8350 as the CPU. These links show my exact scores on 3DMark:
3DMark v1.1 (3DMark13) - 9574:

Unigine Heaven Benchmark 4.0
FPS: 67.2
Score: 1694
Min FPS: 17.1
Max FPS: 152.2

Custom Preset: 1920x1080 Full Screen, 8xAA

Tessellation: Extreme

The R9-280X will get exactly the same scores depending on the vendor-specific model. There will be a greater difference between a Gigabyte R9-280X and a Sapphire R9-280X than there will be between a Gigabyte R9-280X and a Gigabyte HD 7970. That's as precise as you can get.
