Upgrading Graphics Card

Atm i've got a Nvidia 8500GT however, I am wanting to upgrade my graphics card to something which can handle newly realeased games such as crysis, frycry2 and OFP2/ARMA2 when it comes out. Im on a tight budget however, if a card has a good value for money price id probably buy it. I need suggestions on what card to get. I'd like to stick with Nvidia if possible. Also any other suggestions when it comes to upgrading the PC overall would be much appriciated.
