Sup guys, i want to know if my Corsair 450vx PSU will be able to handle my system config with a new graphic card...

Graphic Card: ATI powercoloer HD4850 PCS+ 1GB {this one will be replaced}

And one more question: Which video card will be better for 1920x1080 resolution?? Because i sold my old monitor and i'm using my TV Samsung 40" LCD Full HD now...

XFX GTX 285 1GB

Thank Y'all

BTW: E8400 with any of the new video cards will have bottle neck GPU x CPU?

hold back for the hd-5000 cauz they may be less power consuming.

dont know about the ATI 4890, but the GTX 285 needs a minimum of 550 Watts...

The ENTIRE system needs 550w, not the video card. No video card on the planet requires 550w.
