answer:Oh man, I think my buddy uses one of those…. as a space heater! Seriously, I picked up a fanless GT 240 w/ 1GB for under $100 that would eat any of the 8600-series cards for lunch. I don’t do much gaming myself (not enough to justify a $500 video card), but when I do, I want something decent, and I have to say that I am moderately impressed with that Zotac card of mine. Not only is it faster, it has the side benefits of being silent and of drawing less power. There are other modern cards out there in the same price range (~$100) that could likewise pimp-slap even a dual-8600 rig, so I say upgrade. Just be sure that you get the right one. I wound up with a nice, new 9600-series for my last computer simply because the person who gave it to me accidentally got the AGP instead of the PCI-E version and couldn’t return it. That probably isn’t an issue since AGP slots are rare these days (PCI-E is the norm now) but you just have to be sure.
