Ok, I think I'll run the two raptors in RAID0.
But what do you think I should do as far as rigging the audio goes? I have 5 speakers that are connected to the sub, how would I get the audio from the sub to the PC? Is there a sound card that can receive audio from a sub?
I will take the PhysicsX card off the list, I suppose theres always a chance that Ageia could go down the pan, losing me £110.
Another question I forgot to ask, I read a review somewhere on the web that the 8800GTX uses two 24-pin adaptors from the PSU, seeing as I'm running SLi, does this mean I have to have 4 24-pin adaptors? The PSU I was planning to buy isn't on sale anymore, so I opted to go with this - http://www.xcase.co.uk/acatalog/Thermaltake_Psu_s_.html
is it enough for a big system? Can anyone make a better suggestion?
I will update the list as soon as someone gets back to me on the audio card/PSU. Cheers.
