@tartack could ya answer burnouts queston *pls..
those Intel I7-2600 cpu @3.40GHz are still pretty hot.. 4 core 8 threads but the K version had Unlocked Multiplier great to over/clock lol
umm.. does computer also have intel graphics too ?.. along with the Nvidia GE Force GTX 660..
and is the Windows 10 - 64 bits version 1803 or so..
if so and ya wanna leave hardware acceleration on in opera settings..
ya might could try this..
2.Click on System.
3.Click on Display.
4.Click the Graphics settings link.
5.Use the "Choose an app to set preference" drop-down menu and select the Universal app option.
6.Select Opera using the second drop-down menu.
7.Click the Add button.
8.Select Opera from the list.
9.Click the Options button.
10.Select the High performance option. (If you want lower performance to save battery, then select the "Power saving" option instead.)
11.Click the Save button.
Once you've completed the steps, open Opera and it should now be using your PC's discrete graphics card for rendering tasks.
If you end up experiencing problems, such as high GPU utilization or another performance issue, you can also use these steps to change the Opera graphics preferences to troubleshoot and fix hardware acceleration issues. Bear in mind that rendering issues can also be caused by other problems, such as graphics driver issues. If this is the case, you also want to update your video card driver to resolve any graphics problems.
Note - To Undo - If you want to revert the changes, or you're experiencing other issues,
you can always follow the same instructions, but on step No. 5, make sure to click the Remove button for Opera..
