i am not into high end 250W graphics cards and SLI and computers that suck a kilowatt of power.

i have a intel quad core with 8gb ram but my graphics card is a pretty slow and low power 8600gt. i don't need anything better at the moment.

what kind of graphics cards are possible with 500W? like i said i am not interested in high end graphics cards but probably i will upgrade to something better in a year or so.
