Seeing as I'll be maxing out the RAM in my 8600 this summer and adding a Radeon 9200, I am beginning to think the processor might be a bottleneck. It's a 250MHz 604ev. I suppose ideally I would be looking for a G4 upgrade card, but these are rare and expensive from what I've seen. I found this on eBay with a quick search today: http://pages.ebay.com/link/?nav=item.view&alt=web&id=391051364585 Would such a card be worth the upgrade? It doesn't cost too much, but I'd only be going from 250->300MHz and 604ev to G3? :/ I need some general advise about these upgrade cards. I don't know much about them. Heck I'm not certain if that card I found would even fit!
