550w for 660 enough?

[Bahhoo]

hi!, Ive been looking to upgrade my gpu and I am not entirely sure my XFX 550w will be enough to power EVGA 660 overclocked one. http://www.newegg.com/Product/Product.aspx?Item=N82E16814130833 or even MSI 660ti PE



Cpu: AMD 1090t (not overclocked yet)
Hdd: 7200 rpm sata
3 or 4 case fans, keyboard mouse, dvd drive, ssd

Also i guess ill ask this in same thread but is it a worthy upgrade over single 6870? and would it bottleneck the 1090t or would i have to overclock it, and can i with same psu?

Yes the xfx 550 is enough and here three videos watch them and compare GTX 660 Ti vs. Radeon 6870 http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0CDMQFjAA&url=http%3A%2F%2Fwww.eurogamer.net%2Fvideos%2Fbattlefield-3-1080p-max-settings-gtx-660-ti-vs-radeon-6870-video&ei=DECpUKevLc7qiQKckICwCw&usg=AFQjCNE_JOx1qnSFUkfqBlbQ-RzGt5HYEQ&sig2=ivHz0tVRB4jcKdrk54dscg

Hi

Yes easily...

All the best Brett

Few high-end single-CPU single-GPU setups use more than 350W even with overclocking. A high-quality 450W PSU would cover just about any modern non-SLI/CFX mainstream configuration.
