I have had this PC with a single GTX 260, TX750, and an i7-920 for about 4 years. Around 6 months ago, I purchased a GTX 570. I am currently debating whether I should purchase another GTX 570 and go SLI. The only thing that is holding me back is that im not sure if my PSU that is 4 years old and my CPU will be able to handle two 570's. I am also thinking if its better just to purchase a 670 or 7950.
