Graphic card compatibility

[windsorgolf]

I would like to install a new graphics card in my HP computer. I am running a AMD Phenom ll x4 945 processor, with a ATI Radeon HD5450 graphic card.

What would be a good upgrade?

budget? And psu wattage?

without knowing your bugdet and wattage.
hd 6850 is best from amd
gtx 460 is best from nvidia.

Not the 460 or 6850 because hp desktops usually only have 1 molex connector so maybe a 550ti or 6770
