Best Video Card for a 450W PSU?

Hi,

My buddy just built a PC almost exactly like mine but without a dedicated video card.

Because he got a brand new 450W PSU he does not want to change it right now.

He wants to spend like 100-150 bucks on it.

I thought of the 4850, because it's a low power consuming card and quite closely comparable to the 5770.

What do You think?

Please share You knowledge.

hd 7770 or 7750 run on less power than a 4860 or 5770 another option is the hd 6790

you are risking your pc/psu putting any graphics card from the last 4 years in it.

Tell your buddy to make up a story to take it back to the store and get an exchange for a real PSU
