Hi,
as I said, theoretically your system is good enough to handle this game. And I can't not really give you an advise what components have to be replaced or could be broken maybe. All what I told you are collected experiences over the last years, not only with DS, but also with other hard- and software.
I can't and I don't want to tell you what you should replace or buy, because everyone made his own experiences with different hardware, manufacturers, etc.
I always buy AMD CPU/Video Cards since years now, whereas others prefer Intel/nVidia combinations. You can always start discussions about what is better or faster or more compatible to different games and applications, but this is not what I want to do here now, because it depends on personal experiences and personal preference.
The next problem is, if you decide to buy a new CPU, you will definitely need a new Mainboard, no matter if it will be an AMD or Intel CPU, because none of the CPUs of this generation will match your Mainboard's CPU socket anymore.
You see, there are many problems and considerations which have to be made, so I think there are better places in the internet to inform yourself. It would go beyond the scope of this forum.
