pci-e confusion Tags: SLI PCI Express Components Last response: April 7, 2007 8:25 PM in Components Share jgp4 April 7, 2007 6:29:50 PM Hi need a bit of advice about pci-express gfx cards. I'm looking to upgrade to an AM2 SLi board and put 2 7900GSs in SLi, however I've read that NF570 boards pci-e slots only have 8 pci-e lanes when in SLi My question is - do current cards including the 8800GTX make use of all 16 lanes or will 8 do just as well. I'd rather not spend more on a 590 board but I also dont want my cards to lack bandwidth. Thanks More about : pci confusion apt403 April 7, 2007 7:16:25 PM Dont worry, 8x is fine. There wont be any noticable difference between a 16x lane and an 8x lane. uri April 7, 2007 7:40:00 PM You can see the difference here: http://www.tomshardware.com/2007/03/27/pci_express_scal...

Its to bad that article didnt include more games, COD and Quake are hardly sufficent. emp April 7, 2007 8:25:23 PM IF you haven't both those cards and mobo yet, you'd be better off getting an 8800GTS 320mb and a cheaper mobo than an SLI configuration, in terms of performance.
