Hello! I need some advice about my computer, but wasn't sure where to post this. I'm new to DV editing, as a hobby, just bought a camera, etc. etc. However, have been using Adobe Premiere Pro, After Effects, etc. for a while (don't ask). Question is this: my machine is 2GHZ, 128MB video card, 1GB RAM. I'm thinking about spending some dough for a faster machine with a better video card (512MB) and more RAM. To this point, I've been able to work fine with my current system, but I could always go for more speed, and we're always looking for more power, right? (512MB is tempting me!) But someone told me they thought I'd see enough of an improvement if I added another GB of RAM that I wouldn't need to buy a whole new setup. I need guidance from you experts. Will my current setup, plus another GB of RAM, be sufficient for heavy usage in Premiere & AF, or would I see a sufficient upgrade with a new setup to justify the considerable cost? I'm not looking for perfection, I just want something reliable for some fairly intense editing and effects-work... thanks in advance for your help!
