2 x ati 5850 xfire or 1 x 5870?

sell it and buy a 6970 :)

6970 are supposed to be coming into the market at around £400 -

Following the OP - that's not really in budget. Try to be fair man....

If you have space and your motherboard supports xfire then x2 5850s will do better than a single 5870.

On the other hand the 5870s are really cheap at the moment (£190) so if you could sell your 5850 and buy one of those it would be an upgrade and then maybe xfire that later on- which is amazing performance.

That's my input anyway.
 
5850 in crossfire will beat any single card solution out in the market at the moment, very fast when crossfire'd. You could also look at 6870 in crossfire as they scale really, really well and temperatures are cool when gaming :)

yeah to be fair the 6970 would mean quite a large budget increase, but id hold tight for benchmarks for the 6950 which will be within reach of the OP's budget (he has a 5850 and is prepared to buy another so il assume a budget of ~£250, 6950 will be 250-300) if the 6950 beats a 5850 by 50% then its not far off 5850CF performance as scaling isnt so great with the 5*** series, then at a later date CF the 6950 which would be worth doing as the 6*** series seems to have nicer scaling

Depends on the 12v rail amperage.

I've got 3x 18A rails, and my machine at load pulls 420w from the plug.

50A+ on the 12V is needed.

found the voltages
INPUT
Voltage: 100 – 240VAC
Frequency Range: 47 Hz to 63 Hz
Current: TP-650: 9A @ 100VAC, 4.5A @ 240VAC

Efficiency: Min 82% at full load
OUTPUT
Voltage: +5V +3.3V +12V1 +12V2 +12V3 +12V4 -12V +5VSB
Max.Load:25A 25A 22A 22A 25A 25A 0.8A 3A
 
For reference the Antec TP-650 has 4 x 12v+ rails rated at 22A,22A,25A,25A but with a max load of 648w(54A).

Thought that might help and/or re-assure :)

Edit: Beaten to it. I shouldn't wander off in the middle of composing a reply :D
