Looking for a good new graphic card

[Connorsuds]

Hello,
Im looking for a good new graphic card to replace my gt 9600. money is not a factor but would love to keep it under 200$ the problem is i only have 1 6 pin.
my power supply is at 500 Watt
And phenom 9600 quad core processor 2.30GHZ

1 6 pin would mean a 6850, its a very good upgrade.

If you want to make sure that your processor won't bottleneck get the 6770/6790.
