Couldn't resist any longer watching folks have folk with their 4870x2s so ordered a HIS HD 4870x2 from Auspcmarket.com.au yesterday and it arrived today
Was initially surprised by how small the box was for this 4870x2 compared to other video cards I have. Even the box seemed light ! Already got a Corsair HX1000 power supply provided by the good folks at Corsair to pair up with this video card so all I had to do was swap out the 620W Corsair HX620 and install the HIS HD 4870x2.

for SATA and 4pin molex there's 2 cables for each type
- 2x SATA cables with 4 connectors each = 8x SATA
- 2x SATA cables with 2 connectors each = 4x SATA
- 2x 4pin molex cables with 4 connectors + floppy connector each = 8x 4pin molex + 2x floppy connectors
- 2x 4pin molex cables with 2 connectors each = 4x 4pin molex
for PCI-E express there's 4x 8pin (6+2) pin PCI-E power connectors

Well tried installing Cat 8.9 official drivers and was too smart for my own good and used CCleaner to clean up the drivers and must of wiped out something .net framework. So tried reinstalling .net framework but couldn't load CCC without this error showing
So I uninstalled Cat 8.9 and did the following as outlined
here.
- Check that registry locations are empty:
a. HKCU/Software/ATI/ACE
b. HKLM/Software/ATI/ACE - Check that (Program Files folder )/ATI Technologies/ATI.ACE is empty
- Check (Windows folder)/Assembly folder to see if there's any files with Public Key Token of "90ba9c70f846762e" (Sort by Public key token to get a easier view). All these tokens should be uninstalled by right clicking and uninstalling.
- Check that (Document and Settings)/(User)/AppData/Local/ATI/ACE is empty
- Reinstall Cat 8.9
And got CCC to load with no probs
Out of box GPU1 ran at 74-81C idle while GPU2 ran at 48-51C idle. I took these readings from Everest Ultimate 4.6.1509 beta with fan set at 100%
Did some stock E8600 + stock HD4870x2 @750/900 runs all seems fine except in 3dmark05 seems a bit low ?
3dmark2003 = 77,338
3dmark06 = 16,999
3dmark05 = 22,931
So let's try E8600 @10x500FSB = 5000Mhz 3dmark05 to see if 3dmark05 scales with cpu clocks... surprised 5Ghz 3dmark05 ran just on H20, but was disappointed to see GPUZ reporting crossfire was disabled ... WTF!
So reinstall Cat 8.9 but now can't 3dmark05 bench at 5000Mhz - probably the tiny Corsair Nautilus 500 not taking the extended heat so well LOL or single GPU a lot less stress on overall system than crossfire enabled dual GPUs ? So drop down to 4960Mhz.
3dmark05 @4960Mhz =
33,333 
3dmark06 @4932Mhz =
23,505
3dmark2003 @4932Mhz =
83,665
AM3 @5003Mhz =
294,913 
Yup all above are just stock HD4870x2 speeds of 750/900 for now
