Best Graphics card for my specs

I need a PCI e16 graphics card for my computer so i can play some new games.... For me i want to play the orange box

I have a Pentium 4 3.2 ghz processor

3 gigs of ddr2 ram

400 watt power source

I am looking for the best graphics card i can possibly get for my computer

I dont want a graphics card thatxs gonna need its own power source because thats hard for my simple mind to configure, i need one i can just pop in.

any suggestions?

All you have to do with one that needs its own power source in a cable from the PSU, the same way you plug i a hard drive or dvd drive.

They come with very detailed instuctions, i would really recommened a 8800 GT, this requires plugging into the PSU.

Sorry im not able to tell you what the best card is that dosent need power as i dont remember all of them.
