Radeon 7770 or gtx 650Ti?

[sourodip]

hi guys!! i am planning to get a radeon hd7770 msi power edition but i dont think that my cheap psu can handle it.i have a frontech 450W psu(integrated with cabinet) and now i am planning to get a 500W cooler master psu,so can you suggest me a cheap and good coolermaster or corsair 500W psu with a 6-pin PCI-E power connector?
i also saw reviews from tom's hardware that gtx 650ti outperforms hd7770,so which one is good when compared to price and power efficiency?
i am also thinking to get an amd phenom x4945 processor for my rig,i currently have an athlon x2 245 processor which is overlocked to 3.11GHz and my mobo is Asus M2N68AM-PLUS and does my mobo support the processor as it supports processors upto 95W and i also want to know that will my athlon x2 245 processor bottleneck hd7770 and gtx650Ti?

Thanks....

and what about the psu?

The 650ti is a bit faster than the 7770 not by much, but where I live it has dropped in price to equal the 7770 so probably the better choice depending on your prices...

Careful with the 945 some versions are 125W and will not work with your mobo, make sure to get the 95W version.

PSU go for the CX500, the cheaper coolermasters are not so good!

Yes go and get an x4 945. In the ASUS site it says that it is compatible. I think you should go with the 7770, yes 650 Ti outperforms it, but it's $25 more. Which is not worth it for the performance increase you'll be getting. If you want to get the 650 Ti you should consider the 1GB 7850, because it's performance is beast , compared to the 650 Ti of course.
