Thanks for the reply Jon. I'll look into video cards, etc; I'll admit $500 (which I think is about £250 - £350) was a little more than I would have hoped to pay, but as you say that would depend on what, (and where!) I bought it. Are there any particular models you could recommend as a starting point for my research, (or should I stop being lazy and post a thread in Gear?! :p)?

I have only dabbled myself in flamenco; although I've been playing mandolin for a while and have been considering getting seriously into bluegrass, so who knows?! Time'll tell I suppose

Thanks again for your response, been a great help

Regards,
Chris.
