For the last few years I've gotten by with my GTX 560, it dealt with cod4 sufficiently so I never needed to upgrade as cod4 was all I played.
Now with all these new games about and the need for better gpu's I decided it was time.
I found a barely used evga GTX 680 4gb classified locally that I'm going to pick up tonight.

I'm looking forward to not having to run low settings to get better performance. If I can get a couple of years out of it before needing to add a second card I'll be happy. Paid $300AUD, I think that's an ok price for a top of the line 680. Cant wait to install it!
