I was just at best buy and on hte top shelf was a Visontek xstasy geforce4 MX400 for only $180. That seems like a good price, and i thoght the geforce4's don't come out until next month. I'm thinking about returning my Gainward geforce2 ti440 and buying the geforce4. Only an extra $5. Anyone know how much perfomance increase there would be?
