If I recall, they have to be exactly identical cards in order for SLI to work. If you currently have a Gigabyte 570 GTX, you'll need another Gigabyte 570 GTX in order to SLI. In addition, you'll also need a power supply big enough to handle these power-hungry cards and a motherboard with 2 PCI-express x16 slots. Someone should verify this just to be sure as I'm taking this from other posts I've read.

Correct. You can use different brands of Nvidia cards for SLI provided that they are the same GPU.
