Narrative:

A CRJ2 departed chicago O'hare. He was climbed to 10;000 and vectored to the north departure area. O'hare was landing runways 10; 14R; and 22R. Aircraft inbound from the northeast (kubbs sector of the chicago center) are on an arrival route for runway 22R and descending to 9;000 per ZAU/C90 letter of agreement. An A330 was an arrival from kubbs and came inbound at 10;000 ft and fast. The A330 evidently requested runway 14R and arrival approved his request including a 10;000 ft altitude and faster speed. The inbound route for the A330; and all northbound departures; merge around 20 miles north/northeast. Just prior to this point; I received an intra-facility land line call that said they were slowing and descending the A330. I immediately turned the CRJ2 and climbed him to 11;000 as well as telling him about the traffic. When aircraft are 'turned in' to different runways it is imperative that the aircraft be pointed out to all who may be affected. This is a critical point out that must be made especially when the altitude and speeds are different from the LOA. No point out or information was passed between arrival and myself. Secondly; we have been on fusion radar for 8 days. It has been mentioned to management; and again I will state it here that the fused target and the associated ARTS symbol are such that if you turn the intensity of the radar target up; you cannot tell what ARTS symbol is co located with that aircraft and thus you do not know where that aircraft may be going. Conversely; turn the intensity of the target way down and you can now see what controller and which runway the aircraft will land on. The radar room is getting sloppy. Good technique which includes point outs as in this instance insured that we ran a safe operation. When we deviate from the LOA's we live by; and don't advise our fellow controllers; disaster is imminent.
