Thinking about getting dual GPUs

Hello. So, I have decided to upgrade my PC. I wish to insert dual GPU. But, I do not know which models to get nor how much power it needs to run. I currently own a GTX 660 but should I pair it with another GTX 660 or a GTX 660 ti? Also, I do not know how much my juice my computer will need. Here are my components:

Intel Core i5 3570k

GeForce GTX 660

DDR3 1600MHz RAM (8GB)

Gigabyte GA-Z77X-UD3H Motherboard

1TB Western Digital Caviar Black Hard Drive

600W Corsair CX600 PSU

Will a 600W PSU do me well? Or should purchase a 750W? Any help would be appreciated.

  1. The graphics card doesn't matter, both 660 and 660 ti will work. The 660 ti will pair down to the 660 you already have but I would go for a 660 as it will be cheaper then a 660 ti. The powersupply will be fin.
  2. In my opinion, you should save that money and get a >real< better GPU next year or so, then you will experience a true upgrade and will not depend on wich games you run in the computer to get best performance.

    Remember that not all games can use a SLI configuration and some run even worse than using only one.
  3. I have a 660 and I don't like it. putting 2 together might help in frame rates but they still lack because of the architecture. save as suggested above and buy a better card.

    But, the only problem is that my computer may not have enough power to run 2 GPUs. I would like to upgrade my PSU, aswell, but its always a pain in the ass.

    Alright, what kind of Graphics Card are you suggesting I save up for?
  6. what kind of problems are you having?

    what is the monitor resolution?
