Your PSU should be okay, have you tried using one monitor or two?

One monitor is completely lag free (with Aero on). Adding a secondary monitor with Aero transparency enabled starts the lag.

You'll probably going to need a dual card set-up in my opinion.

Try this:

Download Process Explorer.
  • Go to View> System Information (Ctrl+I) and select the GPU tab.
  • Select all the Engines by checking the check-box next to each one and confirm.

Now you can tell whether it's a GPU memory constraint or a software constraint
by comparing the GPU Dedicated Memory Usage in each configuration.
Tip.
  • You can also arrange the processes running on you system by GPU Usage.

-With 3 Aurora tabs open, Skype and Process Explorer, GPU usage is usually under 2%, GPU Dedicated Memory is at 225MB and GPU System Memory is at 40MB.
-dwm.exe/Desktop Window Manager uses about 0.9-1.1 GPU
-firefox.exe/Aurora uses about 0.6-0.8 GPU
-csrss.exe/Client Server Runtime Process uses about 0.2-0.3 GPU.

So its not a GPU hardware issue.
Its a software issue, where it may lay is a different story.

I guess you'll have to wait for nVidia to update the program and hopefully fix it :/ .

Just read this thread although it's very old , i thought i would comment as i have a similar issue, i have a to end 980ti GPU and a 6700K CPU on a Z170 main board with 16gb of ram, and an ample Tier 1 PSU corsair AX760 This is on win7 x64 ultimate , the lag started when i started to stream video content to my TV using the extend the display option in windows, it causes both displays to run choppy /laggy though the sound is in sync and error free, i have checked the usage of the cpu cores /temp and gpu and neither are getting anywhere near stressed or overheating , if i set the display mode to Duplicate these displays, it runs perfectly , why or what is causing this i can't find a reason for, except it has to be down to Microsoft programing

Hi, I would like to comment because I stumbled upon the same issue and seems my experience could be usefull to narrow it down.
I was using a Phenom II 945 with radeon 7870 on my 144hz monitor and added another 1080, extended desktop and only in a few games windows asked to change color scheme. The second monitor was for speedfan and afterburner. Everything else was smooth as it could with that specs.
I made a portable rig with the specs below, using the same gpu, (waiting for the new ones) and when I extended, got the same, point by point as toby45. Cloned works just fine.
One thing I noticed with afterburner (extended) is that core1 usage gets betwen 70 and 90%, as if some program was running, the other 3 are about 20%. Cloned/single, writting this, 5/9%.
Reading toby45´s I was thinking in the asus mobo, or bios, but empire software´s posts makes me wonder again. Maybe dell uses asus mobo? Win 7 couldn´t be as I´m using the same sp1 in both.
So Intel or Asus are the only variables I can come up with..
(Edit): I don´t know why I read toby had a asus, is it, by any chance? Anyway, motherboard or cpu are my bets.

I was taking a look through this thread and I think I've discovered a possible solution; let me know if it works for anyone. Here is my system information:

I'm running an Asus STRIX GeForce GTX 970 4GB with two Asus 21.5" monitors, 1920x1080p each, on a 750W Corsair power supply. One display is connected by an HDMI cable while the other is connected by a DVI cable. The display is extended, and I've investigated previous solutions listed by users on this thread and everything appeared nominal. Voltages were within spec in BIOS, NVIDIA control panel indicates that performance is optimized for multiple windows, power usage is set to Performance and all available Windows Updates have been installed. Drivers are all updated to the latest stable non-beta version.

As for the solution, try disabling the "transparent glass" associated with Aero without disabling Aero entirely. It completely abolished the laggy/jerky scrolling I was getting in the most updated version of Google Chrome without disabling the window snapping and continuity features. I have no idea how that might work for Internet Explorer of Firefox though.
