LE embeds multiple nVidia (vendor) drivers to support different generations of GPUs, but the 304.xx series is the last one to support 7-series cards and this no longer supports the ABI version we need to support current Xorg with other GPUs (Intel, AMD, etc.) so it was dropped and the oldest driver we include now is the 340.xx series which stops at the 8-series cards. As 7-series cards are now 15+ years old we're comfortable with that - never in our history have we ever pitched ourselves as something to use with old or recycled hardware, and our focus is on current and bleeding edge HTPC kit. In the future we might drop nVidia drivers completely and default to nouveau, but nouveau hasn't been tested (by nouveau developers) on cards that old for a long time either so I wouldn't guarantee it works. Time for a GPU upgrade, or swap to a Raspberry Pi 4 which will probably be cheaper and will out-perform anything that shipped with a GeForce 7-series card.
