I would say that you should certainly be looking to upgrade the PSU. It could well be this is why your 3870x2 failed. Although your 425w PSU may sound just enough, being a generic dell one it won't have enough amps on the 12v rail to supply these cards. At a minimum I'd be looking at a 500W decent branded PSU for you setup.
Thread here about some more unhappy customers who have the 5850.
