SLI - two different GPU's

[VaunSolo]

Hi there! I've looked around a fair amount but as such I've been unable to find a concrete answer.

My Question;
I have a Geforce GTX 560 Ti 2GB GDDR5 Graphics card and I want a second to bridge the two, I have seen a Geforce GTX 660 Zotac for a reasonable price, due to the amount of recording I do I really need to pump up my GPU so reduce low frame rates.

Can I bridge them or should I try and find another 560 TI?

Also, what other Graphics cards can I SLI with my 560 ti?

Thanks in advance


My Rig;
i7-2600K 3rd Gen Intel. (overclocked to 4.0)
ASUS P8z77 - Deluxe
8GB Corsair Vengence 1600mhz
H100 corsair water cooling
Be quiet 750W PSU
Nvidia Geforce 560 Ti 2GB

You can't sli a 560 ti with a 660 gtx, different gpus, only with another 560 ti either 1GB or 2GB, but not the 448 cuda cores one(it's a different gpu).
You can put the 560 ti as a physX card with the 660 gtx.

Put it as a Physx Card?

I wouldn't know how to do that =/
So would be be worth buying to GTX 660 Zotac as a replacement card?

It's up to you, if you want a 660 gtx or another 560 ti, if you can find a cheap 560 ti, it might be worth it.
A 660 gtx is a good option too, for physX card you just plug the 560 ti in the another pcie 16x slot, and then set the physX card on nvidia control panel.

Fair enough, I got the 560 TI a little while ago when I built the rig (Running on limited funds, still overspent a little) assuming it would keep me good for a long while. Since recording I've noticed the frame rate dropping and causing me some pain I figured I'd either invest in a better card or get another GPU I can SLI my current with.

So I can ONLY use a 560 TI to SLI with my current 560?

 

[djangoringo]

Yes, either a 560 ti 1GB or 2GB, but not the 448 cuda cores.

Strongly recommend the 2gb version if you go with a 2nd 560ti. Running 2 cards with different memory capacities in SLI requires additional hassle, not to mention you waste the memory capacity on the card with more RAM.
