Yes - I *think* the main gain comes from the build process not having to put anything on my swap space. I was able to upgrade my 8500 with 8 of the 128 MB DIMMs at about $30-35 per DIMM. I think it's even a little cheaper now, even if you buy them new. When you are ready, take a look at http://w

This is with a 604 processor, right? Then yes, you should try to get a cheap cache DIMM from Ebay. For the 7x00/8x00 machines cache increased performance by up to 20%. I've got a cache card from my 7600 I'm getting rid of. You can contact me off list if you want - otherwise I'll sell it on eBa
