Thanks. I am looking for something that has the capacity for 3 cards
Intel D975XBX. I got it off Ebay a week or so ago with the E6400, 2GB DDR 2 and a 320 GB HDD for the grand total of £55.
I'm running 3 5870s off a 700 W PSU with an Intel E6400. At the wall I'm drawing 670 Watts, so I'm close to the limit, if not over it. I was drawing 280 Watts with one 5870, so each card is approx 185 Watts. I'm using a Coolermaster 700W Silent Pro, which is 80+ Gold certified and only cost £79 inc P&P in the UK.
keybaud may I ask what motherboard you are using?
Depending on the rest of your hardware you can expect that 2 5870 GPUs will draw ~200W each under load.

How big of a power supply do I need for two 5870's? I see a lot of recommendations and people using 900 watt + for 5970's and such. Will these smaller requirements need that much power?
