Just fried 1 of my MP1500 - therefore either I buy a new one ~ £100 or can I replace both with 2 * XP2000 @ £76.38 each. If this can be done is it worth going for the XPs, I'm aware that they are not certified for dual use - how much of a risk am I taking / how much faster will i run? My board is a Tyan Tiger S2460. Thanks
