Recently upgraded my old 700MHz eMac to Tiger and now it's a usable internet machine. That being said, web pages still load fairly sluggishly and as a result I'm looking into upgrading from 384MB to 1GB, only being about $20 to do so. Is it likely the sluggishness would be solved by a RAM upgrade, or is it more likely to be caused by processor/OS/plugin limitations? Don't want to waste money if I can avoid it.
