560ti SLI?

[jthompson1294]

I want to upgrade my 560ti card to sli but i wanted to ask a couple questions first before i do to get more info.

1. How much power do I need? I currently have a 500w power supply.
2. I have a 560ti 448 core card, so can i use any 560 ti card or do i need the exact same one?
3. I recently played Crysis 3 and it brought my card to its knees (which i knew it will), so how much of performance gain should i see with SLI? (I was playing on medium settings at 1080p 4xMSAA, very laggy at ultra settings)
4. Is there a guide to hooking up in SLI mode?

Thanks in advance.

You're going to need a 448 core card and a better PSU.

1) I'd recommend a 750w power supply, a good brand too
2) You need the same card
3) Not much, I'll explain why down below...
4) Here's one: http://www.youtube.com/watch?v=vTz0gyWAsyQ , Setting up the hardware is a piece of cake, just get an SLI bridge.

Now, 1GB of VRAM is beggining to be too little for more modern games. BF3 Maxes out at about 1.5 to 1.7 for most, which is why, even with my old 560 ti at over 1GHZ overclocked I was lagging horribly on ultra settings. This is what I imagine is happening with Crysis. I would do what I did and sell your 560, and with that money and the money you would have used for the second one, buy a GTX 670, it should be around the same price to go that way with the money you get from selling your card and going SLI, and the 670, in most modern games, will have better performance.

would i need a new power supply if i were to go that route and get a 670?
