Hello everyone!

I currently have a XFX GTX 260, and as you all know, it is getting a bit outdated.
I live in Europe and I am a student, that is why I started looking at used GPUs.

I decided to buy a "Point of View GTX 560 ti 2GB", as I got it cheap, and my VRAM would increase quite a bit (896MB ->2048MB).

At first I was planning on putting my GTX 260 as dedicated PhysX, but I just found a guy that wants to sell his ASUS GTX 560 ti 2gb card for a fair price to me.

Now I am wondering if I should buy the ASUS card too and SLI it with the PoV card.
(And still use my XFX GTX 260 as PhysX)

I am currently gaming PhysX games, so I'd like to try it out. And I'd not like to donate my 260 to charity.

My biggest questions are:

1. Is it possible to 2way SLI the 560s, and use the 260 as PhysX? (All different brands)
2. What kind of power consumption would that setup have?
3. Noise and heat of three cards?

My rig is:
AMD pheom x2 9950 BE oc 3.0GHz
Antec 900
Corsair 850w
Ocz 4GB dual channel 800 MHz RAM
XFX GTX 260 896 MB
motherboard (Asus M3N-HT DELUXE)
 

Eximo

Titan
Ambassador
A caution, there are two 560Ti models, the standard and the 448 core version. They have to match in order for SLI.

170W for the standard version, 210W for the 448 core version.

182W for the GTX260.

You'll need 6 6pin PCIe power connectors.

Well I do have x3 PCI-Ex16 2.0 slots, as rolli59 already found out.

Is it actually true that the 560s would have to wait for the 260? It is only handling PhysX.. Man people say a 260 is overkill for PhysX.

And besides, I already have the 260, and only one 560. If it is not worth using all three cards, I will probably just not buy the last 560.

What would the performance difference be between 1 and 2 560Tis?
