Any quad core, Intel or AMD, CPU will typically handle multiple VMs with no problems. The biggest bottlenecks of performance running multiple VMs on a laptop will be RAM and hard drive rpms. Get as much RAM as you possibly can which will minimize your VMs from constantly "swapping" to the very slow hard drive your will receive with your machine.

so if I need a quad-core am I looking at a lot more money? or is there older quad-core options that might actually be less then an i5?
all i5's are dual core right?

Different VM brands act slightyly different when it comes to resources. Some have a larger footprint than others. Some will share a CPU core while others require the entire core to snap to the VM. I've found Sun's (oracle now) Virtualbox performance-wise beats out VMware and Virtual PC. With that said, you still need enough RAM for your host to not swap out to the hard drive, plus enough extra RAM so that the entire VM can be put into RAM and not swap any part of it either.
2GB for a windows XP host, then another 2GB for the windows xp guest should be enough if you are going to run EQ or light apps. So 4GB should be okay. As long as you have a dual core or above, it should be okay. More cores are always better, especially when a processor thread locks that core for a bit, but I run VM's all the time on my dual core without issues.
