I'm trying to extend the life of a computer that was built about 13 years ago. It currently has a Chieftec CTG-400 power supply, an ASRock H61 motherboard, 4GB of RAM, an HD 7770 graphics card, and a 500GB Kingston SSD that is about three years old. The current processor is a Pentium G870, but I'm considering a used Xeon E3-1230 v2. That upgrade would require a BIOS update, and I would use the existing aftermarket cooler with its copper core. Before buying anything, I'll verify the exact motherboard revision, supported CPUs, and required BIOS version. Would the Xeon be capable of handling a GTX 1070 at 1080p, or would it bottleneck the card? I'm also concerned that the 400W power supply may not be suitable for a newer GPU. If I keep using the HD 7770, is 8GB of RAM enough, or is 16GB still worthwhile?

The Xeon would be a major improvement over the two-core Pentium, but it is still a processor from 2012. It should pair reasonably well with a GTX 1070 for older games and 1080p gaming, though modern titles may require reduced settings and could still be CPU-limited. I wouldn’t go much faster than a 1070 on this platform. Sixteen gigabytes is the better choice regardless of whether you keep the HD 7770.
Before spending much on individual parts, compare the total cost with a newer used gaming PC. The motherboard, processor, RAM standard, and power supply are all quite old, and the platform won’t officially support newer operating systems such as Windows 11. The Xeon upgrade can make sense if it is very cheap and your goal is older or lightweight games, but it is not a good foundation for modern AAA gaming.
Go with 16GB if the motherboard supports it. Even for older games, 8GB can become restrictive, and DDR3 is often inexpensive on the used market. The Xeon E3-1230 v2 and GTX 1070 are a workable combination for 1080p, although newer games may be limited by the older CPU. I would replace the aging 400W power supply with a reputable 500–550W model before installing a GTX 1070. Also remember that the Xeon has no integrated graphics, so a working dedicated GPU is required.
If you’re mainly playing older games or using the HD 7770, 8GB may function, but 16GB will make the system more comfortable and is a better long-term choice. For newer AAA games, 16GB should be considered the minimum, while the graphics card and old CPU will remain the larger limitations.
