I'm looking to add more DIMM memory to my PC. I have 2 slots in there for memory cards, one has the original card with 64MB and I added another 128 for a total of 192MB. My question might sound dumb but can I buy a bigger memory card and just pull out the 64MB and pop in more memory, or is it more complicated? It was simple adding the 128, just popped it in and was good to go. I have a AMD athlon 600hz processor which is rather outdated and slow, but I think I need more memory to handle all of the digital photo editing I do. Or maybe a better video card? I have a 3dfx Voodoo3 with 8 MB ram now. Would it be okay to just upgrade the video card and stay with the 192mb memory? Any suggestions would be much appreciated. Thanks!
