KazikluBey, thanks, that chart explained much. I'm upgraiding from an office card, and I'm in on a rather tight budget right now- that is why I'm trying to get something at around 200$. I'm mostly looking on eBay- and there is a new NVIDIA GeForce 7600 GS AGP 512MB DDR2 for 200$ including shipping charges. I had a wonderful 6800 Ultra overclocked to (Core Clock) 425MHz- but it fried. So, I reckon 7600 GS won't be any good for G3? The only game I'm planning to devote my free time to in the near future... I have 2G of RAM and 2GHz processor.
Oh, yeah, another thing- how cautious one has to be when it comes to overclocked cards? Evidently mine burnt, but many people told me that overclocking was an unlikely cause.
