reading the OP's opening post, I was wondering what virtual hardware the OP was running. If using large ram/multiple cpu images, then having several of them over lapping the host hardware is just asking for trouble. With the need for multiple VM's and using a quad + 8GB, then sticking to VM's of single core 512MB would be advisable if you need several running at once.
Of course, if replicating a real world setup, that flexability goes out the door and so you really need to look at spending the money on a dual cpu system just to get enough cores to work with (and by extention, REG/ECC memory to get the large memory needs as well).
