I posted the specifics here pg #262 post #2618.

I'm also running a higher overclock @ the moment. Currently @ 1200MHz Core and +12 Power. VRAM is still stock.

Thanks, I might xFire myself yet.

Yes, 1.25v out of the box, WAY to high, you can usually shave 100mv off that and still get a good overclock, but the cooler does not help, its not all that good, its otherwise a lot of GPU for little money, you get what you pay for.

Its almost a 7950 with a frankly inadequate 7870 cooler, having said that its not really that bad, I have set a low fan profile to keep it quiet, at 75c the fan is running at 40%, with the fan at 50% its running at less than 70c but I don't like the noise.

I also have a Gigabyte 7870, by the next extreme it has probably the best of all coolers, it also cost a lot more money, I have no regrets buying the Powercolor, in fact I rather like it, its a bout 10% faster than standard 7870's like the Gigabyte and the silicone seems stronger.

I paid £174 for it, by comparison I paid £220 for the Gigabyte when they were fresh out, today 7950's cost £230 +, It really is little money fot a lot of GPU.
