Windows 10: What would be a good gaming upgrade from a GTX 770 on my Core2 Quad system?

I'm running an older system with a Core2 Quad Q9550 currently OC'd to 3.6 gig. Win7, 850W PSU, Gigabyte EP45 DS3L board, Asus GTX770 2GB gpu.

The titles I have are Battlefield 1, Battlefield 3 & 4, Battlefield Bad Company 2.

I use my 42" 1080p TV as a monitor.

Is there something that would run on my system that you think would give me a noticeable improvement in the video experience over the GTX770?

 

Intel Core2 Quad Q6600 clocking at 2.40 GHZ Win 10 Upgrade says it is not supported

I have an Intel Core2 Quad Q6600 clocking at 2.40 GHZ Win 10 Upgrade says it is not supported. Dell tells me that it should be compatible as does the Microsoft Windows 10 upgrade site. But every time I try to download the upgrade, a piece of software runs
and tells me the CPU is not supported.

I have looked at all the support sites and went through several suggestions and nothing seems to matter.

I am currently running Windows 7, 32 bit system and want to upgrade. Is there anyone that can tell me why this won't work?

Or should I ****-can this system and never buy another Dell again.

 

Nvidia GTX 770 not working after Windows 10 upgrade from 8.1

Download "Glary Utilities" From " Glary Utilities | Glarysoft"

Go into "Advanced tools", under the "optimize & improve" menu click on "driver manager" then select the tab "update"it will scan your machine and hopefully find any driver updates. I know after Windows 10 came out I had to update my 770. Good luck.

 

Nvidia GTX 770 not working after Windows 10 upgrade from 8.1

So, after I upgraded to Win 10 this morning Windows is not recognizing either of my monitors. I am stuck with 1024 x 768 resolution. My Nvidia GTX 770 now shows this error in the device manager "Windows has stopped this device because it has reported problems.
(Code 43)"

I have gone to Nvidia site and downloaded, then installed, the Windows 10 driver and no change. I am thinking very hard about rolling back to Windows 8.1........

Any other suggestions? Please and thank you!

*****Up date 12/11/15: I did end up rolling back to 8.1 back in August. This past week I decided to give it another go. The upgrade to Win 10 was a complete success. My GTX 770 now plays well with Win 10.

I hope everyone else has had similar success!

Thank you to all of you that took time to reply!

Cheers!
