What's a good video card for the next year?

Which of these video cards is a decent investment just for the next one year?



XFX Radeon HD 4770

BFG Geforce GTS 250

Diamond Radeon HD 4850



KEEP in mind that I have a 500W psw (20A+20A on dual 12V) and I play on 1400x900 res (19" lcd)



Thanks!|||Deffo Diamond Radeon HD 4850|||huh?|||I have the BFG Geforce GTS 250, it can play all the newest games (e.g. mw2,GTA4) on the highest settings with no problems and has awesome 1080p blue-ray play back. I love it. Its a grate card for the price.



The GF GTS 250 is 475W so you are good on the PSU too :)
