Hello,what would be a good upgrade form a 8600 GT?

Any of the top cards available today will be it.

I use Two lightning Extreme MSI Cards in SLI myself. It is very pricey but worth it to me.

What's your budget? Do you have an preferences on what card you want (e.g. black color, from EVGA, Nvidia)? What resolution do you use?
