Firstly disable ati overdrive download riva tuner 2.24c and install - find your way to the low level overclocking and fan adjustment part and make sure you reboot when it asks you to for both oc gpu and fan control defaults - i think your memory should do between 1100 & 1200 or close to and the gpu i cant remember either, but take it up in increments of 5 to start, and when you get to artifacts go back about 15 and to be on the safe side.
The 4870 will oc nicely, but not all games repond to oclocking the graphics, as some are cpu limited, and only respond when you stretch the cpu, which is a shame, but from what i can gather, and from some of the benchmarks -crossfire will responds in some of these cases.
Go to the download section at the below site for riva tuner, and any other utilities :

what more important for performance . gpu or memory clock?

ive set my 4870 to gpu 840 memory 1150

and its rock solid stable
