Considering a graphics card upgrade. What should i get?

[steviet32]

Hi everyone,
Can you please advise what would be a good graphics upgrade for my pc. My setup is:

ASROCK M3A770DE motherboard
500w power supply
12GB DDR1333 RAM (Can change to 8GB 1600Mhz Ram as two out of four sticks are clocked down)
AMD Phenom ii x6 1045T
Naff HD4350 graphics card(to be upgraded)

I was considering HD 7950 or HD7970 or maybe Nvidia equivalent.

What would you guys advise?

1920 x 1080 on HD tele. Or my 4:3 monitor 1280 x 1024

Don't think my 500w PSU is of a suitably high standard. Was one I got with case. How would I go about ensuring it is good enough? And can you recommend a good PSU? For a reasonable price?

What effect will a PCI-Express 2.0 motherboard with a PCI-Express 3.0 card have?
