Personally I prefer AMD and if/when I upgrade my wife's PC, I'll just get another AMD processor. She's actually quite jealous of my macbook though, so when it's time to upgrade her desktop, I'll probably just end up buying myself a Macbook Pro and I'll give her my Macbook (if I can get away with giving her the hand-me-down
).
But seriously, back to the video card thing. I was talking with my boss today and he pointed out that my spending over $200 on my Geforce 3 Ti200 really wasn't that bad since I'm still using it six years later. It has actually been migrated through 3 system upgrades, so I guess the money was well spent. It still is working great for me though, so there's no need to upgrade yet. At the rate we're going with my very our current desktop, we won't need to do another major upgrade for a while. The next upgrade will be some more RAM and then eventually I'll put in the maximum processor upgrade that the motherboard will take. Then finally if the time comes to put in a new motherboard, I'll invest in another good videocard that can give me another great 10 years.
