CPU/RAM Vs SOUNDCARD - Performance/Latency upgrade

If you're happy with your existing interface, the answer seems to be a bit of a no brainer.
 
You'll notice a HUGE difference if you upgrade your core elements of Mobo/CPU/RAM
 
You might also be able to save a bit of cash if you can source identical RAM to your existing chip(s), this will of course depend on Mobo compatibility and how many slots/sticks are in the equation

Thanks guys.  Makes my decision pretty clear  ;>

A real quandary.  A new computer is probably the cheapest way to improve your ... software.  Makes sense - more memory, more speed, yada yada yada.
 
On the other hand, RME has some of the best drivers in the business, which means less strain on your system, less latency, etc.
 
If I had to make a choice it would be a computer.  One can't be sure until you switch everything out, but you are likely to get much better performance from a new CPU etc.  while latency probably won't be more than w/ the RME, everything else will in the virtual world will - effects, soft synths, not glitching at making changes while playing back, etc.
 
As far as sound - converters are one of the last things that make a difference after source, room, mic, preamp.  Don't discount it, but you are talking about the last couple of percentage of quality much easier achieved w/ proper recording/mixing techniques and arrangement.  Hugh or one of the SOS testers used the emu as his benchmark since he found it top in the class of what might be called prosumer interfaces.  this was a few years ago, but converter tech has been good for a while and hasn't got that much better for the price range.  RME would be better, I imagine, but not night and day.  Instead, you get a computer that makes engineering easier, and fun.  Which will help your sound more than a few extra dBs of headroom.
