I have one doubt I am planning to buy sapphire Raedon hd6670 1gb ddr3 graphic card( http://www.flipkart.com/sapphire-a [...] CTDGQW)its a pcie 2.1 but i am using Intel Dp55wb( http://ark.intel.com/products/4116 [...] rd-DP55WB) which supports only 2.0 ...i know that pcie is backward and forward compatible but i have a doubt about power supply as pci 2.1 can supply more power via itself instead of using extra connectors so does it mean that when i put the card in my mother board which is pcie 2.0 can it power the card(as i didn't see any other extra power connectors mentioned in the card)
The Radeon HD 6670 gets all of its power through the power lines in the PCIe x16 slot. The card doesn't use any more than 63 Watts maximum while overclocked and running Furmark GPU stress testing.
PCI Express 2.1 increased the power output from an x16 slot to 150W from 75W.
You won't have any problems running the Radeon HD 6670 in a PCIe 2.0 x16 slot.
Thanks a lot brother
Also would you recommend this card for medium gaming?i was using nvidia 9600gt which is dead and planning to install this card as its replacement i am looking at same or little better capability compared to nvidia gt9600
