I've done the rather silly move of trading my HD4870X2 for a GTX285 and some cash, and bought a second GTX285. The reason for this is the need for a CUDA/OpenCL-supporting multi-GPU setup because I need to code a GPGPU university project, but it was still silly money-wise (and feature wise, given the lack of DX11). Anyway, I'll chew myself out over that later, but here's the one thing I haven't thought about: On my main rig, the Hiper 880W PSU will power those two beasts without any hickups. Since my upgrade paths usually take the GPUs from my main rig and put them in the secondary rig once I buy a new GPU setup, this means both GTX285s will end up in my 2nd rig probably around the end of this year or something like that (xDevs SLI hack FTW). Now, my Q9650 rig in the sig is running an Enermax Modu82+ 625W PSU. It has sufficient PCIe power connectors to make it happen, and according to this review it is unlikely that I'm gonna run out of wattage on the PSU, although it will sweat at load (Will three 25A 12V rails survive the load ?). Opinions guys and gals ? Will it blend....erm...run ?
