Soldato
Phoned up this morning and changed my OcUK order to Gigabyte, theres no way I could wait another week, now lets hope they get them today...

The gap between the FPS average and the 99th percentile frame time tells the story of the Titan X's smoothness and the R9 295 X2's stutter.
We can understand in-game animation fluidity even better by looking at the "tail" of the frame time distribution for each card, which illustrates what happens in the most difficult frames.
The 295 X2 produces 50-60% of the frames in our test sequence much quicker than anything else. That changes as the proportion of frames rendered rises, though, and once we hit 85%, the 295 X2's frame times actually cross over and exceed the frame times from the single Hawaii GPU aboard the R9 290X. By contrast, the Titan X's curve is low and flat.
Check out those smooth frame time plots for the Radeons with Mantle. All of these graphics cards handle this game well in 4K, but the Radeons are just a notch better. As evidence of that fact, notice that the R9 295 X2 trails the Titan X in the FPS average but is quicker at the 99th percentile frame time mark. This outcome is the result of intentional engineering work by AMD and Firaxis. They chose to use split-frame rendering to divvy up the load between the GPUs.
In this way the game will feel very smooth and responsive, because raw frame-rate scaling was not the goal of this title. Smooth, playable performance was the goal. This is one of the unique approaches to mGPU that AMD has been extolling in the era of Mantle and other similar APIs.
I expect to see game developers and GPU makers making this choice more often in games based on DirectX 12 and Vulkan. Thank goodness.
This whole test is pretty much a testament to the Titan X's massive memory capacity. I used the "Ultra" texture quality settings in Shadow of Mordor, which the game recommends only if you have 6GB of video memory or more . And I tested at 4K with everything else cranked. As you can see from the frame time plots and the 99th percentile results, the Titan X handled this setup without issue. Nearly everything else suffered.
With 4GB of RAM onboard, the R9 290X and GTX 980 handled this scenario similarly, with occasional frame time spikes but general competence. With only 3GB, the GTX 780 Ti couldn't quite keep it together.
Meanwhile, although the R9 295 X2 has 8GB of onboard memory, 4GB per GPU, it suffers because AFR load-balancing has some memory overhead. Effectively, the 295 X2 has less total memory on tap than the R9 290X. Thus, the 295 X2 really struggles here. My notes say: "Super-slow ~7 FPS when starting game. Occasional slowdowns during, should show up in Fraps. Slow on enemy kill sequences. Super-slow in menus. Unacceptable." The fix, of course, is to turn down the texture quality, but that is a compromise required by the 295 X2 that the 290X might be able to avoid. And the Titan X laughs.
Here's another case where a game uses Mantle on the R9 295 X2 and performs nicely in all of our metrics, with a relatively smooth and sensible frame time distribution. Remarkably, this is also another case where the R9 295 X2's performance matches that of the Titan X almost exactly. Seriously, look at those curves. There's much to be said about the virtues of a single, big GPU.
My notes for this game on the R9 295 X2 say: "Seems good generally, but occasional hiccups that take a while." Take a look at the frame time plots, and you'll see that I nailed it. By contrast, the Titan avoids those big hiccups while also keeping frame times low overall. That reality is best reflected in the "badness" metrics at 33 and 50 ms.
Despite that oscillating pattern, the Radeons spend almost no time above the 33-ms threshold. That's good. Better is the Titan X, which spends very little time above the 16.7-ms threshold. It's almost capable of a "perfect" 60 FPS in this game at 4K.
Chap I spoke to on the phone this morning said they where expecting delivery's at 12pm

So this is the daddy just now then? Trying to keep up with GFX cards and worse still Intel’s naming of its CPU is a nightmare if like myself you have not been following for a good few years. Just now I don’t know what is what on the CPU scale its all architecture this and architecture that and something bridge etc.
I kind of think when I get a new PC later this year it’s the GTX 980 I will aim for. Only got a 27” screen so anything else is over kill and a waste if I’m not wrong.
I guess I will get my OCUK next week ?
Going to have to give the guys a call...
That is pretty much me today
Hahaha brilliant where do you get this pics from?
Don't worry buddy they'll get them today.
You'll be having a play by tomorrow
Why not swap for another £20 like I did, they have plenty of Gigabyte cards
