Just a little warning.
A few days ago I snapped up a couple of "faulty" HD 4870 X2s on eBay for just 60 euros. They were on a buy it now and the seller obviously didn't know how much they were worth, not that I was complaining at the time
So today they arrived, two reference Sapphire models and a copy of 3DMark Vantage. They are monstrous card, that's for sure.
I was frustrated at first as I was told by AMD that they would require an 8 pin PCI-E connector and would not run with two 6 pins. And secondly because they would not fit in my case, even though it is a full tower. So I had to run an open test bed hardcore overclocker style
Which made the HD 4870 X2 look even better, the black PCB is gorgeous.
Anyways, I tested one card and was happy and disappointed when it prompted me to connect the right power connectors (I am hopeful that it will work when I have an 8 pin connected).
Second card went it, posted and booted into Windows before it blue screened. I put my system back to default setting and booted into safe mode which went fine. Rebooted again and booted into Windows successfully
I have been kindly told by Windows that my card will be downclocked to reduce power consumption and that I should buy a shiny new PSU. I must obey!
And overclocking has been disabled until I connect the 8 pin (FU!)
