Briefly.. assuming I get my rig working again (Bah!)...
In terms of everything, whats better, a single GTX 280 or a pair of GTX 260s in SLI? I have th e260s, which I managed to get for slightly less than the cost of a 280, because some stores dont bother checking their prices properly. However, does the 280 outperform the SLI pairing? I had a look for reviews, but drew a blank so far. Cheers all :)

Hmm.. does certainly seem that way. On the downside, I just saw the max watts for the 260. 580 odd?? Works out at about a 1600 watt PSU for the rig! Maybe this needs a rethink :(

I'm not sure if I understood your power concerns, but I think your 1000W PSU (Corsair, Antec...???) would do the job. You could also email them and ask which PSU they used :D

The PSU is a Jeantech (Store brand), although the ratings are good and they have, generally got good reviews. I was looking at the power draw for the card at 500 odd watts- given I use 2, I wonder if the PSU will be able to cope at full stretch. Having said that, I dont think that as an SLI setup the cards would be used to full cap. At a quick calc under full load, we have about 1000W just for the cards, plus, the current setup, which is aroundabout 200 watts, i reckon. I think its best to leave th epsu as is, and se what happens- if i need a bigger one it might be time to call it a day<g> :)

Yeh, just use one until you get a better PSU. If it doesn't work.
