I have just bought MSI Radeon 9800pro 128 mb 3dCard by replacing my old Fx5200 card. Is this a good card (R 9800 pro) for playing new games on medium sttings. MSI RX 9800pro-TD128 (Model) Memory Interface = 256 bit RAMDAC = 400Mhz Memory = 128mb P. Pipelines = 8 Coreclock = 378MHz Memoryclock = 338MHz One thing I want to ask i.e. My card is low memory clock 338MHz where it must be 680 Mhz(Given in ATI website). What is the difference in 338 and 680 Mhz. For what thing memoryclock and coreclock is used for?
