PowerColor AMD/ATI Radeon HD6670 2 GB DDR3 Graphics Card on P5NESLI?

Hey guys,I have a question regarding HD6670 Radeon and ASUS P5N E SLI Compatibility?
Hi,Im currently using g Geforce GT240 1GB DDR3 graphics card but it has stopped working since a couple of days.I am now planning to purchase PowerColor AMD/ATI Radeon HD6670 2 GB DDR3 Graphics Card there have been multiple websites which i have gone to which suggest that Asus P5N E Sli does not support the new AMD Cards but this is something i have seen only for HD6850.I m unable to see anyone using P5N E SLI using HD6670 Graphics card.All i need to know is will this graphics card work on the configuration below

Motherboard:Asus P5N E SLI

Processor:Core 2 Duo E6750

RAM:4GB DDR2

Hard disk drive:1.7 TB

PSU:400 Watts Zebronics Platinum

Based on that i would go ahead and book the 6670 Graphics card.Please advise me if this would work for sure?

Would appreciate any help on this

thanks in advance.
