i currently have a Dual 2.0 Powermac with 1.5 GB Ram, Radeon 9600, WD Raptor 37GB 10,000rpm with Tiger Loaded, 160 SATA secondary drive and a NEC 3500-AG 16X DVD writer. Now i seen the new imac with Front Row and built in iSight and just love it! What I'm asking is if i sell my Powermac now and get the new iMac will i see a huge performance hit? I do plan on upgrading the ram to atleast 1GB or more. I basically surf the web do some downloading, occassional HD video viewing and editing, and music creation, but rarely play any games. The machine I have now suits me well but i love how the iMac takes up barely any space, and I could use all the extra room i can get. Any help is appreciated. Thanks.
