If you're running a 32-bit operating system and are using an Nvidia GPU you better start thinking about upgrading to 64-bit if you want to continue to get game ready drivers. Yes, you read that correctly. Nvidia will no longer provide drivers for 32-bit operating systems after the 390 driver release. Not surprising. Existing drivers will probably keep extreme legacy programs on older operating systems going for another 10 years or so. That should be adequate. And new games usually require more than 4GB ram (32 bit OS limit), so I don't see a problem with this.
