I would get an ek extreme water kit ddr4 ram (idk if they are backwards compatible but they should fit into ddr 2 ram slots)an Intel Core 2 Extreme QX9650 and be done with it. Oh Oh and a samsung pci-e ssd.
Wow, so much bad advice in one post.
Different DDR types are not backwards compatible, DDR4 won't fit in DDR2 slots and the a QX9650 wouldn't work with DDR4 anyway. The only Samsung PCIe SSDs I know of are M.2 drives, which that mobo lacks a slot for. Also, a platform that old probably couldn't boot from a NVMe device anyway. Finally, spending hundreds of dollars on a water cooling kit when budget is clearly tight makes no sense. That money would be much better spent upgrading system components.
If the OP upgrades his CPU, he should upgrade mobo and RAM at the same time.
