ADDITIONAL COMMENTS: basically i just want the best card that my current system can handle. Im will to spend a bit extra on card if it will work with current system. Just recommend any card you feel would suit me and then i can check on prices in australia. Have been gaming on consoles till now and would like to give pc gaming a go now. Also the 7600gs fan is struggling to spin so its time to replace it and making some seriously weird clicking and scrapping noises (visually the fan gets pushed to spin and then slows down and pushed and slows etc....) so the purchase will be pretty soon.
I appreciate all input greatly. i am not that great with this stuff. bit of n00b still but trying to learn it all
PS have a laptop with 9600gt in it would like better performance than that if possible at the very least.
17 amps on the +12v rail is quite low. An HD5750 may work but you will be pushing things. An HD5670 or one of the low power 9800GTs without a power connector is probably the most I would recommend. For comparison those should be nearly twice as powerful as the mobile version of the 9600GT.
Whatever card you get is going to be limited by your processor on a lot of current games. 2.1 ghz is low by today's standards. Ordinarily I would say overclock it which the processor can handle quite well but your board is Intel so it is highly doubtful it allows for overclocking. Looking up the board on the Intel site it doesn't even list your current processor(or any core2duo) on the compatibility chart so I can't even guess at an appropriate upgrade if you were interested. I guess you'll have to live with being cpu limited in the more intensive current games until you are ready for a new system.
