I almost bought that, too. I, too, have the GF4 MX420 that came OEM with Dell 8250. Decided to wait on a card and consentrate on other upgrades first. Need a new power supply to replace the meek 250w OEM. Gonna need another 512RDRAM for the new games out there. And just bought a 200gb EIDE HD to add to my 120gb. I'll wait to see the 6800GT go down to $150 probably next summer. Just saw the 6800STD for $200 after MIR.
