Old GPU in new system

[rowens.wds]

I have windows 10 on a ryzen 3 1300 12 GB ram and gtx1080 ti gpu. I play a lot of older games 5-15 years. I'm no stranger to tweaking settings to get the games working. However with this machine I have had an absurd time getting the settings just right. I have an old gtx 460 and I'm wondering if it might be better to install the old gpu and run older games through it instead of the 1080 ti?
I have tried to install the 460 but it doesn't seem to let me run two driver versions. And defaults to the newer card for pretty much everything.
How can I isolate the cards so the 460 is used for some games but the 1080 is still there for other games?
Does it make sense that I might have easier compatibility with the older gpu?

Note: overall graphic or performance dont matter to me as much as having a game I can play without spending two days of crash and tweak.

You will need to work with older drivers for the GTX460 since latter drivers revisions have phased out support for the GTX460. My simple solution is to rebuild a cheaper system with only the GTX460 as the discrete GPU(meeting full system's power requirements). The GTX1080Ti is more for the latest games out there.

You could also try running the games in compatibility mode > Windows 7. BTW, by crash, do you mean a system reboot during game taxation?

By crash I mean allot of different errors. Usually just closing the game mid play, sometimes freezing. I've also had allot of script error or missing dll or ini errors and I have to go dig up old versions of direct x or windows updates to fix. Rarely I'll get fatal errors blue screen usually having to do with the gpu.

I presume you're running Windows 10, alot of older games just don't play nice with win10 even in compatibility mode. It might be better to run a virtual machine with an older os for your old games. Not sure why you're running 12gb of ram though it means your either running 1x8 and 1x4 or 3x4, either way you're holding back your system, you should be running either 2 or 4 matched ram modules for maximum memory bandwidth.
