I suggest you check newegg for a 4670 chipset card with rebate or lifetime warranty, such as some models of evga. You have to register them online to get the warranty. The 4670 is a mid range card that may not require you to upgrade the power supply. If you have at least 300 watts in a fortron fsp, aopen, corsair, antec, seasonic, pc power and cooling, enermax, or ocz, any of those may be able to handle this card without an upgrade. If you want a high end card, be sure to check for recommended 12v amp ratings. I use 40 amps as the minimum for a high end video card.
