Hello everyone,

My current build is as follows:
CPU: Intel Core i5-4670K 3.4GHz Quad-Core Processor
CPU Cooler: Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler
Motherboard: Asus Maximus VI Hero ATX LGA1150 Motherboard
Memory: Corsair Vengeance 8GB (2 x 4GB) DDR3-1866 Memory
Storage: Samsung 840 Pro Series 256GB 2.5" Solid State Disk
Storage: Western Digital Caviar Black 1TB 3.5" 7200RPM Internal Hard Drive
Video Card: EVGA ACX Cooler 03G-P4-2784-KR GeForce GTX 780 3GB 384-bit GDDR5 PCI Express 3.0 SLI Support Video Card
Case: Fractal Design Define R4 (Black Pearl) ATX Mid Tower Case
Power Supply: SeaSonic X Series 1000W 80 PLUS Gold Certified ATX12V / EPS12V Power Supply
Operating System: Microsoft Windows 8 Professional (DSP) (64-bit)

Now that the ROG Swift PG278Q is officially announced, I was wondering if a single gtx 780 will be enough to play games on ultra at a smooth frame rate. I know that g-sync will help out even if it drops under 60 fps, but do you think I will need to SLI in order to fully appreciate the monitor or to use the monitor to begin with?

I read on the other threads that for 1440p, I may have to bring the texture quality down to play games smoothly with gtx780, but will end up looking better than 1080p. Is this true?

At the moment I think I have 3 choices.
1) buy Swift PG278Q and use single GTX 780
2) buy Swift PG278Q and another GTX 780 for SLI
3) wait for vg248qe g-sync pre-installed (1080p gaming)

Please let me know what you guys think.
Thanks in advance!

G-sync offers a new way of syncing the display and video card. In the past, a monitor at 60hz, updated every 16.7ms, with no exceptions. A 120hz monitor updates at 8.3ms, with no exceptions. If you use v-sync, so that you do not get tearing, and your FPS are not the same as your refresh rate, some frames will have to wait 33.3ms, while others will wait 16.7ms. In the case of 120hz monitors, some will be 8.3ms, while others are 16.7ms and longer, but they cannot have frame times between. This can make games feel a bit jittery, or stutter.

G-sync allows the monitor to change it's refresh rate to match the GPU's frame delivery. As soon as the GPU creates a frame, it sends it to the display, and the display updates its image. That...

If I'm not mistaken, the SWIFT is 120 Hz refresh right? In that case, a single 780 will not suffice at Ultra. SLI would be your best bet, but if you're fine with playing on ... high? (just a guess) you could very well take advantage of the 120 Hz refresh rate.

Having a higher refresh rate does not increase the requirements for smooth game play. The fact is G-sync monitors are all 120/144hz unless they are 4k. G-sync gives the most benefit at sub 60 FPS. So yes, a single 780 will give smooth game play, smoother game play than on a normal 60hz 1440p display. However, it is possible to use more GPU power for higher frame rates, as the monitor will support up to 144hz, though 140 or less is optimal (use FPS limiter) as it has been shown that if you get too close to the refresh cap, it introduces v-sync like latency.

that is not completely true, a high refresh monitor will make game play at 60 fps look better. but yes you are correct in that to get the most from a high refresh rate monitor you do want high fps.

you can get a VG248QE monitor now, and wait for the price of G-sync to start going down, then buy the DIY kit (currently $200) and install it in your VG248QE. that is exactly what i am doing

Because you are also getting G-sync with variable refresh rates. This makes lower FPS much smoother. 50 FPS on that monitor will be much smoother than on a 60hz monitor, and even smoother than other 144hz monitors due to G-sync and you can't buy G-sync without 120+hz.

Thanks all for the reply!!
I'm a noob when it comes to graphic cards and monitors so I guess I am having a hard time understanding the correlation between refresh rates and FPS, and what exactly g-sync is capable of.

From what I researched even if I tone down the quality to get a decent FPS on a 1440p monitor, it will still look better than 1080p ultra. Is this true?

As ChrisR83 mentioned, I had the opportunity to buy a g-sync pre-installed VG248QE ( I am situated in Japan, and the DIY kits are not available), but I couldn't pull the trigger because of the no warranty issue, and the idea that SWIFT was coming...

I sort of understood that with my current rig, I won't be able to fully utilize the SWIFT monitor. My question is do you think I will still be able to enjoy gaming on it, until I decide to SLI or if I wait for the maxwell GPU etc.?
It's just a matter of money, because if I decide to get the swift, and you guys feel that I need a second gtx 780 to
enjoy gaming at all, then I will probably have to go with the VG248qe, but if I can still enjoy gaming for a few more years with just one gtx 780, I will be able to save up for a new GPU in the future to fully enjoy the monitor.

Sorry for the long reply.

If you use v-sync, so that you do not get tearing, and your FPS are not the same as your refresh rate, some frames will have to wait 33.3ms, while others will wait 16.7ms. In the case of 120hz monitors, some will be 8.3ms, while others are 16.7ms and longer, but they cannot have frame times between. This can make games feel a bit jittery, or stutter.

G-sync allows the monitor to change it's refresh rate to match the GPU's frame delivery. As soon as the GPU creates a frame, it sends it to the display, and the display updates its image. That means if frames take 8ms, 10ms, 9ms, 12ms, 10ms... to create, the refresh times will match those frame times. That means everything is delivered in a smooth fashion without tearing, regardless of what your frame rate is.

A 780 will fully take advantage of G-sync. It may not be as good as 780 SLI, as that increases the FPS and further makes things smoother, but the difference between G-sync and not using G-sync is just as big if not bigger than 60hz vs 120hz.

Thank you Bystander for the detailed feedback!

So I think its a matter of whether or not I want g-sync, and not really having to do much with 1440p/1080p or frame rates...

I guess I can go ahead and wait for the swift monitor, and just go with the single 780. Hopefully g-sync will be able to help me out. If it doesn't seem to be enough, I will lower my settings and wait for the new GPU, or get a second 780...

Thanks all for the replies!

I'd say the monitor choice is for those who both want G-sync and 1440p, and less to do with the 144hz, though that is a big bonus as well. There will be other G-sync 1080p monitors too, and even a 4k G-sync monitor (expect that one to be 60hz as there isn't an interface for 120hz at 4k yet).

And remember, it's G-sync on or Ultra Low Motion Blur (ULMB) on they can't be used together, G-sync on will provide a 60hz 60fps v-sync on experience with variable refresh rates from ~ 40fps - 144fps (having v-sync on right now with a 40fps - 144fps range just feels like absolute garbage with current 60hz screens).

ULMB on will be identical to current high Hz monitors since G-sync is off and will require the same high and constant FPS requirements with no FPS dips but if achieved (by lowering settings) will appear sharper during movement. Both modes have their pros and cons.

Thank you bystander. Yes, presumably, more g-sync monitors are on the way. Hopefully soon because I really want a new monitor.. 4K is something I don't think I will be able to achieve anytime soon, so I will wait for reviews on the Swift monitor and if it looks okay, I will purchase it. If not wait for a 1080p g-sync monitor...

This is my first time hearing about ULMB... Is this available in the swift monitor, or is this something else?

ULMB is a low persistence mode, like lightboost, that reduces the appearance of motion blur to almost 0, but I'd image most people who want a G-sync monitor, do it for G-sync and not ULMB, not that it wouldn't be cool to use on a game you can get to 100+ FPS all the time.

The ULMB mode is an improved version of lightboost, which does not mess up the colors, like lightboost does.
