Considering SLI Tags: Nvidia Graphics Cards SLI Graphics Product Last response: December 21, 2011 4:54 AM in Graphics & Displays Share Kalzakov December 20, 2011 6:06:47 AM Hello ive been considering SLI and ive stumbled across a problem, My Current graphics card is a EVGA GTX 570 HD 2.5 gb and for some reason theres no reliable seller for these anymore. So my questions is what else can i SLI with and what do i need to know in terms of rules when sli two different cards? Thanks More about : sli perfectblue a b U Graphics card December 20, 2011 6:25:12 AM For optimum operations of SLI, you should get another GTX570 with 2.5GB RAM, shader and clock speed as same as the EVGA card you own. The speed can usually be adjusted in any card by overclocking. If you dont meet these criteria, you TWO cards will perform roughly twice the performance of the LOWEST spec'd card. Eg: if you pari a 2.5GB with 1.25GB card, your SLI will operate at 1.25GB. TheMaristBoy December 20, 2011 6:26:21 AM technically, you can SLI with another 570 regardless of specs like ram. just make sure its a 570 gpu.

Otherwise, an SLI rig will scale quite well, but not x2.

So 570 with 570, not 570 with 580. joedjnpc a b U Graphics card December 20, 2011 8:23:03 AM Kalzakov said:i was under the impression same series as in 5xx same GTX? No mate, that's an ATI feature, you can pair any 5xxx or 6xxx series cards, but to be honest it's fairly pointless since the pair will run at the lower clocks of the two cards.
