Sounds a silly question, but what does everyone preffer to rip & convert there DVD's too? The reason I ask is I'm starting to rip DVD's via DVDdecrypter on Windows XP. My machine is the following spec: P4 2.66Ghz 1Gb RAM NVidia GeForce MX460 Graphics Card (64Mb) However, I want to get the following iMac in a few months: 2.8GHz Intel Core 2 Extreme 2GB 667MHz DDR2 SDRAM - 2x1GB SuperDrive 8x (DVD±R DL/DVD±RW/CD-RW) ATI Radeon HD 2600 PRO with 256MB memory Now I know that the iMac has dual core, but as they are based on Laptop Hardware, from what I can gather, do they actual make a difference in terms of quality. Not bothered about time. Does HB use the Graphics chip for converting file types or is it just the CPU. I'm a fan of *nix systems & would preffer to do it on the iMac. But if it doesn't make a difference I would rather start ripping/Converting now so its ready for when I get my iMac/ TV. Cheers for any help/ advice!
