Hello all, I'm pondering a few potential hardware upgrades to my system in order to getting running more efficiently and one of the things I ultimately need to do is get a new video card... I'm currently running 1 Nvidia NVS 290, 1 Nvidia FX 570, and 1 ATI Firemv 2400... The ATI is not 64-bit compatible so I'm looking for an upgrade there, but am not sure what to go with. The two things that I'm considering now are: 1) Get an NVS 420 quad card, remove one of the other Nvidia cards, and ditch the ATI card... or 2) Try to find a dual DVI PCI replacement for the ATI card (this is just a "basic" PCI card I believe -- It's in one of my three somewhat smaller white slots -- not sure what it's technically called but I think it's just PCI). My question is... What sort of good dual DVI PCI replacements options are there? I've been looking at some stuff online and it looks like the majority are the big PCI x16 cards, but I don't have any of those slots remaining.... Only 3 PCI slots (Would like to just add another 290 card because you can get them online cheap, but not an option). Or does it make more sense to just look at spending more money and doing the full upgrade to the NVS 420 card? Thanks for your help.
