I have a Dell Inspiron Athlon 64 X2 5000+(2.60 GHz, 512Kx2); 300W and at +12V --> 18amps; 22inch E228WFPWide Aspect Digital Flat Panel. I need to replace my 256MB Nvidia GeForce 8600GT-DDR3; what is the best I can get and potentially run 2 monitors? I only run a few games but they were starting to die with the current card. I was looking at the Geforce GT 440 1MB but it wanted 22Amps at +12V and 300W!! I am not particular about the card; just want it to work.
As the above posters said, buy a HD 5670 or HD 5570 ( 5670 would be better ). As iamthecrowe said, you would be fine with a 300 W PSU with the 18 amps on the +12V rail. If you are going to run games on 2 monitors, you should go for the HD 5670.
Also you miss-pelt 440 GT 1'MB'
All, thank you very much. I am going to go with the 5570....and after reading this site it sounds like one can build a system for a comparable price and I will go higher with that system including the 2 monitors!
