I have an old laptop with a pentium dual core and 2 gb ddr2 ram, and i was thinking of using it as a secondary pc while streaming. do you guys think that its enough or do i need an upgrade?
It all depends on what you're going to be doing on it while streaming on another machine.
Word-processing, accounts and browsing the Net should be OK. I think too many pieces of old PC gear gets thrown out while still having the chance of a longer working life.
