I remember when testing my A500T with Blizzard 2060 and 2 MB Megachip2 the max speeds it could get thru the chipset were between 0.8 MB/s and perhaps 2.1 MB/s and that was when the graphics were handled by a PicassoIV leaving the chipset on very low strain. So with those speeds you can't expect too much. But everything that runs on the processor/memory loop is a different thing. I remember when launching my A500T first time with Blizzard 2060 using just the ECS chipset I was quite disappointed what was happening on the screen. Under two weeks I had acquired a RTG card - what a huge difference!
