I'm wondering if current applications, like MS Office, Photoshop, DVD burning apps, etc can take advantage of Intel dual core CPUs? I'm looking to get a dual core, 1.6Ghz, 1GB RAM, built-in video from Dell. I already have their Inspiron 6000 1.66Ghz, 2GB RAM, 128MB ATI video. The RAM runs at 533Mhz DDR2 but the dual core can take up to DDR2 667Mhz.
