7870 power efficiency... Tags: Radeon Graphics XFA24 February 1, 2013 1:12:11 PM So I was planning to buy an MSI GTX 660 Twin Frozr III OC Ed but then, moments ago, I checked the prices.. It was of great surprise to me to know that the Sapphire HD 7870XT Boost Ed became cheaper for about $18 compared the 660... I am certain that the Sapphire HD 7870XT Boost Ed will bottleneck with my Core i3 550... I read on an article that Radeons have these technologies called ZeroCore wherein it virtually uses 0 Watts when in idle mode... Correct me if I'm wrong, but does the 7870 consume more power than the 660? because the 7870 requires 2x6pins while the 660 requires only one. Soon enough, my specs would be like that of the following: OS: Windows 7 Home Basic 32-Bit CPU: Intel Core i3 550 @3.2 GHz GPU: Sapphire HD 7870XT Boost Ed RAM: G.Skill Ripjaws 1x4GB DDR3 1333 HDD: Samsung HD502HJ 500GB 7200RPM SATA PSU: Seasonic M12II 620W CHA: Fractal Design Core 1000 MOBO: Asus P7H55-M LX Firstly, I would like to know if the CPU and the GPU would ONLY have a minor bottleneck. and Lastly, I would like to know if the Radeon 7870 is more power efficient than the GTX 660. -Thank You in Advance!
