You have a Core 2 Duo model so your options are more limited. You can upgrade to the 3.33 GHz Core 2 Duo CPU but thats not much of an improvement. I would pass on doing that. As to replacing the GPU card: Yes that would resolve the GPU failure. I would go with the Radeon HD 4850 with 512 MB. As for the SSD yes that can give your system a lot of zip but you would then either need to buy a fairly large drive to get the deeper storage, or you'll sendup giving up your optical drive for the second drive. Instead I would go with a hybrid SSHD drive. Because of your systems limited SATA ports I/O speed SATA II (3.0 Gb/s) I would recommend going with the [https://www.seagate.com/www-content/product-content/firecuda-family/firecuda/files/firecuda-ds-1903-1-1606us.pdf|Seagate FireCuda]. It offers a SSD cache to improve its speed and yet it offers the deeper storage of a traditional HDD. I would go with at least 8 GB of total RAM. Your system can support unto 16 GB of RAM. I would also recommend going with MacOS Sierra (10.12.x).
