I've gotten my ABiT Siluro GeForce 4 Ti4200 recently (Thanks mom!!!) and I was wondering about the difference between the PCB board. In accordance to what I think I knew, GF4Ti4200 uses a 6-layer PCB board instead of GF4Ti4400/GF4Ti4600's 8-layer PCB board. What's the function of the PCB board? What difference is there in a 6-layer and a 8-layer board? Regards - eddy05, the always-wanting-to-know-everything.
