I am looking to upgrade my graphics card in my dell XPS 8300 and Im not entirely sure on which power supply to buy with it. I have always heard a lot of people tend to cheap out on the power supply when it is one f the more important parts.

The mainboard is 0y2mrg. ( I think )
The current power supply is 460w.
The current graphics card is AMD Radeon HD 6770
The Processor is i7-2600 @ 3400MHz
The RAM is 16384MB DDR3 1333MHz (4 x 4096MB)
The operating system is Windows 7 Ultimate
The HDD is 2TB (2 x 1TB RAID 0)

I was planning on getting a 650w-750w power supply replacement with a price of about $200 or less.

As for the graphics card, i'm aware there are a number of cards I can get and not have to replace the power supply but I was hoping to get something such as the following:

I just want to make sure it will work with what I have.

(Im not exactly an expert on these sorts so if I left any significant information out be sure to let me know :p)

About what strength should the power supply actually be with this set up and do you have any recommendations other than what I have as a plan currently? ([Example] Upgrading something else instead of the graphics card)

PS: I only go up to 1920 x 1080 as I play on a LED HDTV that cannot display resolutions higher than this.
