SLI - Help!

[Miles121]

Hi Guys

I bought the following last year from Overclockers, love it

Battlefield War Commander Intel Core i5 2500K 3.30GHz @ 4.60GHz DDR3 Limited Edition Quad Core System [BF3-PC]
Power Supply: OCZ ZS 850w PSU
GTX 570 1280mb

Stupid questions of the day!

1. If want to SLI this rig do I have to have 2 cards of exactly thes same spec?
2. Would the additional card come with Sli bridge connector (or do you not need those anymore).
3. If I don't need 2 cards the same, what would complement the GTX570?

Hope this makes sense, thanks in Advance

Hi Rusty

Motherboard : ASUS P8-Z68-V, found the SLI cable in the box, thank you for that.

The GTX 750 , was a windofrce that I note doesn't appear to be on Overclockers anymore?

Sorry whats VRAM?

Thanks
