Looking for new GPU

So its the holiday season. Finally saved up enough to buy a new GPU. Been rocking the AMD 6870 for the past two years. I have $300 to spend on a new gpu and im thinking of switching to nvidia but whichever one is best for the $300 price range then i will go with that.

My speccy info.

I'm also thinking of getting a triple monitor setup. but if there's not graphics card in the $300-350 price range that can handle that its cool.

 

Looking at your specs, a 280x or a 770 would be better for around $300, but if you can wait a bit wait until the custom 290's come out because they are awesome.

Looks pretty damn good.
