Yes, more cores will help.
I recommend getting more RAM, too. You asked a question on another thread about GPUs. Spend whatever money you were going to spend on a nice GPU on RAM instead.
Thanks for the advice.
If it's an either or situation, which would be best, please:
- six cores and 16gb RAM (AMD FX6300 4.1 Ghz)
- eight cores and 8gb RAM (AMD FX8320 4.0 Ghz)
I'd go for your first option, with twice the RAM and 3/4 the processor cores.
