Your thought is pretty good - a pentium anniversary should be the perfect dolphin CPU.
If you can overclock it to around 4Ghz you should be able to play SMG1/2 in Fullspeed 99% of the time (I had performance issues with the "Fire Gobblegut" boss with a i5 Haswell @ 4Ghz, but the rest of the Game was okay)
Zelda will slowdown in the "Hyrule Field" Part - just search the forums on this topic
Maybe someone who has a GT 640 can tell you if this chip is fast enough for 3xIR ... I'm not sure
Slighty more costly would be a "Radeon R7 265" or a "Geforce GTX 750 Ti", but those are definatly fast enough for 3x IR (and you can play new PC Games too).
Ram Speed matters - but in general it maybe produces 1-2% more performce overall - so it's hard to measure.
It's only interesting for people who use CPU build-in GPUs (Intel iGPU, AMD APU etc.) - there it can have a big effect on performance
So save the money and get 1600
The PSU should be enough: (though the buldtin PSUs of cheap cases are sometimes shit)
- The Pentium should have a TDP of around 50W (But will need additioonal power if you increase voltage due to overclocking)
- a GT640 cosumes max. 25W
- the rest of the PC will take maybe additional 30W on full load
