4870x2 poor performance HELP! (info/benchies incl.)

Hello Children :) 

Recently purchased a Powercolor 4870x2 and since installing it, i've had a lot of problems getting a decent performance out of it. ANY help/suggestions/opinions you could offer would be greatly appreciated on how to fix my problem. I have no idea what to do now.

Current setup:
> Powercolor 4870x2 (with 8.9 catalyst drivers)
> E8400 Core 2 duo @ 3.0ghz (had OC'd to 3.5ghz, no obvious difference)
> 2gb DDR2 1066mhz RAM
> Gigabyte X48 Motherboard (drivers installed)
> Cosair 750w TX PSU
> Samsung Spinpoint F1 500gb HDD
> Samsung 245b 24" Monitor (playing at 1920x1200)


(I previously at an E6700 @ 2.66ghz and an 8800GTX and got much more playable framerates in most games)

So that all looks fine right? Well.. according to:

- Crysis and Crysis Warhead it enables me to play at 'Very high', 'High' and 'Gamer' with an average of about 5-10fps. Totally unplayable.

- GRID, i get 50+ fps at max settings (8xAA). Sure, thats perfectly great but according to benchmarks i've seen, i should be seeing double that.

- COD4 - 40fps+ at max settings - Again.. should be getting much higher FPS's.

Everything is fitted and plugged in correctly (got some second opinions) and obviously games DO work.. just not as fast as they should with my setup.

Here is a Furmark/3dmark06 (basic) benchmark and the CCC/CPU-Z/GPU-Z



As you can see, at 1280x1024 and no AA (cos i have basic 3dmark) - I get just 15004 score. Not what it should be.

More info:
>CPU temp idles at around 30c, GPU with fan at 40% around 40c.
>GPU in a PCI-E 16x 2.0 slot (that my motherboard has)
>BIOS has been reset, voltages and everything to AUTO
>Have all latest drivers
>Have tried with a p35 motherboard and 2gb DDR3 RAM - No change
>Have OC'd CPU to 3.5ghz - No obvious change
>Case Ambient temperature - 40c

So... do i have a duff GPU or am i missing something? HELP!

Much appreciated.

Any idea what the problem could be? Perhaps a faulty card?

^^yeah, in windowed mode the card only uses 1 core and those sm scores seem quite low

or maybe it's not properly powering up the second core when in 3d mode, might be a driver issue...

edit: lol I don't know, looking at the X-bit labs review and the 3dmark scores are pretty close

Well, my only suggestion is to try and remove Speedstep / C1E. It's because in certain setups I have experienced problems with them, basically what happens is that Speedstep is working even on full load (Games, Orthos), so effectively lowering the clock speed permanently, causing poor performance.

Make sure you have the lates drivers #1 and #2 in Catalyst click on Info Center then click on graphics hardware. It should read Primary Adapter an "Linked Adapter". If it does not read like this then your card is only runnning one gpu, hense lower performance. I heard if you go 64 bit this will correct the issue with the Sapphire 4870's. For others i do not know. I would take the card out and reinstall the card and drivers first before anything. Email me back and let me know I would like to help you if I can.
