Hi: First of all, you can use any of the daughtercard processors, I have an 8500 and I think our motherboards are almost identical. It's really easy to install and requires nothing other than a card to do. Just pop out your old one, and press the new one in *tightly*! As you said, adding a second, larger HD will be a "no-brainer," but consider buying a new SCSI card (ultra-scsi or faster) and a matching HD so that it wont slow down your newly sped-up machine. Buying a G3 or G4 processor also eliminates the need for upgrading your L2 cache, as it will act as L3 cache and slow down your machine. I originally upgraded my cache, then to a G3 processor and after I took the cache (1 MB RapidCache) out, the system seemed more responsive. You can max out your VRAM to 4 MB, but it is rather expensive (maybe 30-40 per 1MB chip). I would suggest buying a new video card such as the iXMicro ultimate-rez that are like 75 bucks. Good luck, and email me with any questions you might have.
