I think some confusion as to why RAM 'increases' the speed of a PC or Mac and therefore the question here. Also PCs do not have Chip/Fast/32bit RAM debacle too.
I will bow to the superior Amiga knowledge about the merits of CPU and various types of RAM on every Amiga model produced.
But as far as PCs and Intel Macs go...they are running bloatware....adding more memory just alleviates the seriously bad code running on your CPU box. So...if you have Windows 7 and 1Gb of RAM and simply shove in a stick of 2Gb memory to make 3Gb (negating a speed increase due to dual channel mode) the only reason your speed 'increases' is because your bloatware OS has more room to stretch it's bingo wings code
I suppose some Amigas will benefit from RAM over CPU in some cases but overall it's not quite as general a problem.
You can run XP quite happily on 100mhz if you have 256mb of RAM...but 64 or even 64mb on 300mhz is useless and 'slower'
What you should also factor in though is replacing hard drives with state of the art lightning fast solid state Compact Flash drives on any AGA machine too....this also makes a massive difference on PCs and will improve your perceived speed on an Amiga too I guess. Some companies produce 2.5 IDE hard drive sized solid state drives with the SATA/PATA IDE connectors all fused in a handly little plug in replacement box which work a treat on the A1200/600 and A4000.
