Everyone tells me Radeon is a better card, but I've allways bought Nivida running a 8600GT myself it doesn't have HDMI but it can process 1080P no problems through DVI without the sound!
I'm sure these 8600GT are like £40 now?
But heard good things about The Sapphire or Asus HD 5670 £60 odd pounds bargin!
If you can find a cheap one of these it might do the job but I would just go for a 5670 for the money!
