I just bought a new 24" widescreen LCD a few days back. The new higher resolutions I'm running has me considering a new video card. I've been out of the loop for a little while, so I'm trying to get cought back up. I found the 8800 GTSes were falling into the price range I had in mind. There's a huge range in their prices though. For a bit over $300, you can get one that has 320mb of memory on the card. For right at about $400, you can get one with 640mb. Is it worth the price difference? I'm thinking that $400 is a bit more than I was looking to drop, but if it's worth the difference I could probably do it, though. Anybody got any insight? Articles, comparisons, reviews you could point me to?
