Upgrading Graphics Card, Need Help Selecting New PSU

This is my current Build (It was a cheap PC)

CPU: AMD FX-6100 3.3GHz
Motherboard: Gigabyte GA-M68MT-S2 (rev. 3.1)
Memory: Patriot Signature 4GB (2 x 4GB) DDR3-1333 Memory
Storage: Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive (x2)
Video Card: AMD RADEON HD 6450 1Gb
Power Supply: 500w Winpower Quiet PSU Power Supply (Model: AD-F520A2-30)

The Graphics Card is a very poor one (and a horrible PSU), and I was going to order a new one over the weekend, and was thinking about getting a GTX 670 as it has relatively good performance compared to the price. I also plan to expand my current setup, so I was thinking a 750W would suit well for some future expansion, if so, what power supply should I get? I do rendering currently and plan to game with it once I get my new graphics Card.

Edit: Changed the post since, I now know a little bit more on power supplies.

Definetly do not try to run a GTX 670 with that PSU. That is a very low end PSU. It's 500W rating is bogus. With 2 x +12V rails rated at 15A and 16A it is basically a 350W PSU. And a poor grade one at that. According to this ad, it doesn't even have a PCIe 6 pin connector for a GFX card.

The GTX 670 requires 2 x 6 pin PCIe power connectors. It requires 170W maxed out which means it will draw over 14A from the +12V rail

I have done a lot of reading on PSUs and realise that my question was pretty stupid, I changed the first post to reflect that. Am am however still not 100% confident on selecting a power supply by myself. I had a look around and found the Corsair HX Series HX750 750w has really good reviews, and is pretty efficient. It looks like it would be fine and definitely suit expansion. Should I get this?

Your choice is a solid one. The Corsair line is one of the best. And 750W is enough for upgrading in the future.
Here is a tiered list of PSUs to get an idea of which are good and which are not.
