My 4870 has arrived!

very good... have you been able to get by the 790mhz core... ?

I have now ! Working on higher (I've done 870 stable with 4500 RAM but heat is a killer!)

100% stable, ~25% performance increase in Crysis, and a huge COD4 boost + over 790/4000 . Not sure why I'm seeing a non-linear performance increase for a 10% memory clock increase and 6.3% core clock increase, like a bottleneck was alleviated somewhere, but I'm seeing the same thing in World In Conflict too... not quite as much but more than a linear increase.





At these speeds:


At 790/4000 I got 20.2 FPS at identical settings.




World In Conflict:

790/4200:

Average fps: 29
Min fps: 17
Max fps: 45



840/4400:

World In Conflict DX10 *MAXIMUM* settings for everything, plus 16x AF and 4x AA *with* transparency AA (8x in control panel, 4x set ingame like above), third run out of four tested (840core/4400ram):






Really odd... that's a 31.1% increase in max FPS in World In Conflict (bench is capped at 60FPS it seems), 13.8% in average, and ~5.9% in minimum (negligible in actuality).
