Help me choose the graphic card...

From the last few days the tomshardware community has helped me a lot to find the ultimate budget pc for me.....Now the fight has come down to the last round...
For the gpu I have decided to get myself a nvidia 9600 series card, but I just can't choose the right one...Help Me....Tell me which one of the following will be perfect for me.....(I look for visual performance. It does'nt matter if the card makes too much noise or if it gets too much hot until and unless it melts...) :

1- zotac 9600 gt (non amp) 512 mb gddr3
2- sparkle 9600 gso 384 mb gddr3
3- xfx 9600 gso 768 mb gddr2

Thanks for reading guys......

At stock speed, #1 is best. When overclocking, #2 will be better. Do not get #3, ddr2 = slow.

No, the ram size won't make much difference for these cards. Larger ram size only really helps at high screen resolutions with high end gpus like the hd4870. I have a 9600GSO and I get 12566 in 3dmark06 with it overclocked.

Uhm...Do I expect any big performance differences between the zotac 9600 gt (non amp) 512 mb and xfx 9600 gso 384 mb?

@ gamer21; No and no.
