Rewinding the clock a few years back, I didn't use Dropbox all that often - even the 'cloud', I never used often. I relied mainly on my Google account, and my QNAP NAS. When I started here at TweakTown, I needed something where I could access all of my work, on any machine, on any operating system, anywhere.
I jumped into Dropbox when I purchased by Galaxy S III, as Samsung were handing out 50GB of free Dropbox storage - so I thought I'd use it. From there, I've uploaded tens of gigabytes of data to the cloud, and have it synced across multiple machines, operating systems, and even on my NAS.
Your first step, of course, is to ensure you have a Dropbox account - if not, you can sign up here.
I'm going to presume you're using Windows here, so once you're signed into your Dropbox and have some files synced, you'll have a 'Dropbox' folder in your Users directory. This folder, is the folder that everything is stored in, and you'll access this constantly.
Not too long ago we tested our SAPPHIRE Radeon R9 290X Tri-X GPUs in CrossFire at 4K, with some very surprising results. The Tri-X cards are some of the fastest consumer GPUs on the market, with some crazy headroom for overclocking.
But, how does Team Green fare at 3840x2160? That's what we're here for today. We have two reference NVIDIA GeForce GTX 780 GPUs in SLI that we're going to test on our Seiki Digital 39-inch 4K TV.
We've already tested our SAPPHIRE Radeon R9 290X Tri-X GPUs in both 4K at stock, and overclocked, but the numbers when overclocked were not great, considering the mammoth memory bandwidth numbers we saw.
We were not that impressed with the added performance from the overclock, given the increase in audible noise; when those fans spin up, it can get quite loud.
We overclocked our already-overclocked R9 290X past its Tri-X settings, to an insane 6.2GHz memory (from 5.2GHz on the reference R9 290X). This resulted in some absolute benchmark-busting memory bandwidth. Increasing from 320GB/sec on the reference R9 290X, to a huge 422.4GB/sec on our overclocked Tri-X GPU.
A couple of days ago I wrote an article, testing out two SAPPHIRE Radeon R9 290X Tri-X GPUs in CrossFire, at 3840x2160 - or 4K - or Ultra HD. We had some surprising results, but I thought we could overclock them, and see what we can find.
Firstly - hot DAMN do these Tri-X GPUs overclock! I went from the stock 1040MHz Core, to a huge 1200MHz. As for the RAM: the SAPPHIRE R9 290X Tri-X has some serious overclocking power! We were able to drive it up from 1200MHz all the way through to 1650MHz, completely stable in all of our tests bar one.
This is just completely incredible, as it provides us with an insane 422.4GB/sec of memory bandwidth. This is an all-important step of overclocking, and provides some much needed headroom when we're gaming and testing at an insane 3840x2160.
My family is enjoying some food and each other, I'm enjoying a nice alcoholic beverage, while I sit here in my shorts on a nice, sunny day here in Australia. What better time is it to test out some Radeon R9 290X GPUs?
I've played with the Radeon HD 7970s, and while they perform well, the new Radeon R9 290X GPUs are based on the Hawaii architecture, play much better with higher resolutions such as 3840x2160, or 4K, and no longer require a physical CrossFire connection.
We're still testing them on our Haswell setup, but we're soon moving to a Sandy Bridge-E rig, where we'll re-run the benchmarks we've already run, and are running today. This will be coming in the next month or so, we have nearly everything, we're just waiting on a few more parts.
Ah, Battlefield. I have so many memories of the franchise over the years, but Battlefield 4 is becoming a quick favorite of mine. Even more so at 7680x1440.
Testing BF4 can be quite hard, as there is no built-in benchmark. I decided to run the game on 'Radio Communications' map, with 32 players in the game. This gives a much, much better in-game feel of the frame rate of a proper multiplayer game.
I ran the test for 5 minutes each time, to get a better minimum/average FPS result, too.
The last time we looked at the AMD Radeon HD 7970s in CrossFire, we were running stock clocks. But, you are on a site called TweakTown, so we decided to tweak our cards. Throwing some overclocking onto them, and re-running our tests to see how much of an improvement overclocking had at 7680x1440.
We were able to drive our cards up to 1200MHz on the Core, and an astounding 1800MHz on the Memory, which you can see, above.
We'd like to thank Corsair, AMD, GIGABYTE, AMD, Patriot Memory, and InWin for making this all happen - without you, we couldn't have done it.
Now I'm sure you want to know the exact specs of the system, so here we go:
- CPU: Intel Core i7 4770K "Haswell" processor w/Corsair H110i cooler
- Motherboard: GIGABYTE Z87X-OC
- GPUs: MSI Radeon HD 7970 Lightning BE (2x)
- RAM: Corsair Vengeance Pro 16GB kit of 1866MHz DDR3
- Storage: 240GB Corsair Force Series GT (3x) and 480GB Corsair Neutron GTX
- Chassis: InWin X-Frame Limited Edition
- PSU: Corsair AX1200i digital PSU
- Software: Windows 7 Ultimate x64
- Drivers: Catalyst 13.11 Beta 6
Disclaimer: Star Citizen is in very, very early alpha form, and in no way, shape or form, represents the final game. The final game will include so many other parts of the game - so we're just benchmarking the Hangar Module today. Keep this in mind, I've simply run this benchmark to see what the future of PC gaming holds in store for us.
If you'll rewind nearly two decades now, you'll find yourself in an era of PC gaming at its golden age. There was a young, talented man known as Chris Roberts, who was the brainchild behind one of the biggest space-based games of all time: Wing Commander.
We've tested our NVIDIA GeForce GTX 780 SLI and GeForce GTX 770 SLI GPUs, but now it's time to test out what AMD's cards can do. Our first venture into the AMD side of things at 7860x1440 is with two Radeon HD 7970s, but don't worry, we have some R7 and R9 GPUs on their way, so keep checking back to see how these GPUs perform at the insane 7860x1440 resolution.
We chucked our new Tweakipedia build under the bus a few weeks ago, seeing how it would fare with two NVIDIA GeForce GTX 780s in SLI at 7860x1440. That resolution is quite strenuous on any system, mixing three 2560x1440 panels and the latest games with two of the fastest GPUs is always fun.
Well, NVIDIA were kind enough to throw two GeForce GTX 770s our way, so we're going to see how these much, much cheaper GPUs do at the same resolution through the same benchmarks.
First, the GeForce GTX 780 will set you back around $649 through Newegg, while the GTX 770 is priced at just $399. I expect the GTX 770 to keep up with the GTX 780, but I think it will ultimately not fare as well as the GTX 780 thanks to the uber-high resolution. Let's get into it!
