I have a hard time agreeing with that. If you buy an SSD, your computer will feel much faster. Putting in 8GB of RAM will also make the machine a little snappier, as it will keep more in the RAM for fast access. The RAM will only run you about $40-50 too from NewEgg.
An SSD would only make programs that are installed to it load faster. The 15 seconds less load time is not worth the $100+SSD. And for all we know his computer might not even support sata.
Considering the processor is 2ghz and the ram is 2gb, there's no way his motherboard could support 8gb. I'm guessing his computer is from <200, back then 4gb is the max. You also need to realize that ddr2 ram is a lot more expensive than ddr3 ram. ddr2 ram is $120+ for 8gb. Even if the motherboard has a 8gb capability, it would most likely be bottlenecked by the cpu. His best bet will be to replace his current ram with 2x2gb 1066ghz ddr2 ram.
But before anything can be determined for sure he needs to post more specs.
