I picked up an HP Pavilion p7 from around 2010 with an AMD Athlon II X4 645 and 6GB of DDR3-1333 memory. I only want to add a basic, inexpensive graphics card so the system has dedicated video output and can handle web browsing, media playback, everyday tasks, and some older CD-ROM or DVD-ROM games. I'm not trying to play modern AAA games or upgrade the whole computer. A card with VGA or DVI would be ideal for use with an older monitor. What's the cheapest practical GPU from that era, and are there any low-cost models that still perform reasonably well for very light gaming?

For hardware from the same general period, look at Nvidia’s GeForce GTX 400 or 500 series, or AMD’s Radeon HD 5000 and 6000 series. Older cards from those families can be very cheap on the used market and should handle basic older games much better than a GT 710. Check the power supply and available space first, since some models need additional power connectors or are too large for an HP prebuilt.
A GeForce GT 710 is usually easy to find for around $20 and would work for basic display output, browsing, and media use. Just keep expectations low—it’s extremely weak for gaming, even by older standards. For your use case, though, it can be a simple plug-and-play option if you find one with the right connector and a compatible low-profile bracket.
A GT 1030 would be a more capable low-power choice, especially if you happen to find a used one at a reasonable price. It’s newer than the other suggestions and may be overkill for simple browsing and DVD playback, but it uses little power and can handle light older gaming. Make sure to avoid the slower DDR4 version if performance matters, and confirm whether the card has VGA or DVI for your monitor.
