I'd suggest upgrading your power supply and getting the card you want, most video cards on the market require 300 to 350W power supplies or more. And the ones that don't, usually aren't worth buying anyways.
I started a thread about differences in graphics cards on 7/3/07. This lead to the NVIDIA 8500 model. So know I'd like to know what ppl thought about this model and which one is a better bargain?
Newegg lists 26 different NVIDIA 8500GT models. And my power supply on my HP Pavilion a6157c is 250W. They are all a good bargain, with the most expensive being $99, but requires a 300W supply, which I don't have. So what's recommended out there with regards to other specifications on cards???
