660ti SLI PCI-e 2.0 or gtx 680 PCI-e 3.0 Tags: Gtx SLI MSI PCI Express Graphics Last response: April 11, 2013 9:40 AM in Graphics & Displays Share citizen197 April 11, 2013 9:28:13 AM Hi everyone, I have one msi gtx 660ti/oc running PCIe 3.0, I7 3770 ivy bridge on a 55" 3d 240hz 1080p sony TV My Asus sabertooth Z77 only has one 3.0 slot so my questions is should I add another 660ti in SLI at 2.0 or should I just buy 1 670/680 and use it at 3.0 Thanks guys! More about : 660ti sli pci gtx 680 pci ubercake April 11, 2013 9:40:19 AM That motherboard has two PCIe 3.0 slots which will run at 16x with a single card and 8x/8x with two cards. Two 660tis will give you better performance than a single 680, but you could probably get good money for the 660ti. I would buy the 670 or 680 (which, in itself is an upgrade over a 660ti) and grab another 670 or 680 in the future by selling the 660ti you currently own. Can't find your answer ? Ask !
