Morning folks! Happy friday... I'm in the market to finally update my iMac. I have an old iMac G5 that I bought in 2006. And even though I love it and it's served me well for these past 5 years, it's finally starting to slow down and show its age. Alot of the programs I like to run are starting to get really sluggish, etc (especially photoshop). Anyhow... I'm waiting until Apple unveils the new iMacs in a few weeks (hopefully!) but there is one thing I've never really understood... processors! I understand hard drive and RAM, but dont really know much about processors and video RAM... i want to learn about them and understand how they work so i can make the right decision when i purchase my new iMac shortly. any good websites or articles you all can recommend to help me understand processors and their speeds? and video ram? how important it is... etc? my current iMac is 250GB of hard drive, 2GB RAM and i think the processor is a Core 2 Duo 2.0 something... haha. i dont understand it really. with 128MB of VRAm.
