I jus upgraded my pc with a 475 watt psu and i want to go buy a new agp video card.....i currently have an ATI Radeon 9200 video card but was wondering wat AGP card would be the best to buy now!? any suggestions would be great!?
Well I believe the best card available for an AGP system is the HD3850 but depending on your cpu you may be wasting money for little or no improvement over a slower card. It requires a minimum of 450W PSU with 30A (360W)on the +12v rail(s). So check your new PSU +12v rail. You could also look at in decreasing order a HD4670 AGP, HD 4650 but you would probably do just as well with a 2600XT card and your 475W PSU should handle all those with no problem. I heard a rumor that Powercolor had a HD4770 AGP... I have no idea why since the cpu for nearly all those systems would most likely bottle neck it!
Well my guess is you barely have 22-24A available from your +12v rails so max would be the 2600xt I think. That might be pushing it. I am not sure of the HD46xx amperage requirements. I suggest you google that.
