GTS, not GTA.
Here is a good shop, it is the one I deal with.

I built my whole new gaming PC over Christmas from there.
Here is the card for $329

The GT is less, but not as good.

The GTS has a new GPU design.
You can Google the card too to find it cheaper.
It is perhaps the best gaming card out now.
Some new 9800s have hit the market, but they are not as good as the 8800 GTS.
Later 9800s will be, then I will upgrade mine perhaps.
But mine makes mincemeat of any game out right now at maximum settings.
Also the Evga brand is one of the better ones, and they often superclock it from the factory over Nvidia's stock specs.
