If you have enough money, I think you can change the CPU and switch to Athlon II X4 635. The price is estimated to be around 300 yuan. Add another memory card. Graphics cards can be colorful or Galaxy. Of course, colorful ones are more expensive, so Galaxy GT240 is recommended. As for the optical drive, it depends on what kind of optical disc you burn and the noise requirements. Personally, I think Samsung's is still very good

If the funds are limited, then replace the CPU with Athlon II X4 635, and the graphics card is the Lieutenant General's version of Galaxy GT220!

The above is purely a personal opinion. If there are similarities, it is purely coincidental.
