Not from my experience. I've got that video card in an 866mhz PC with 256mb of RDRAM and it handles MSFT Flight Simulator-2000 with no trouble at all. And the graphics in that software are extremely demanding on the system.

Hi,
If you are refering to the notices that you get when you configure a Dell System using RDRAM, the conflict issue is between the Video card and CD ROM choice.

Thanks for the replies. I'm configuring my system, so I don't want to buy into any problems. An 866 with 256 RDRAM looks very sweet but my cashbox is maxed out at a 733 with 128. There's always room to grow, though, isn't there?
Thanks, again.
