jaypatel, it is not the manufacturers fault. it is the reference design. Ramdacs are built into the chip now. If you look on older boards such as a old matrox 2 a ramdac is quite a large chip, but they are integrated into the core of the chips now. RFI filters, cannot be made that crappy, the cost of the stuff that a RFI filter is made of is neglible. Really following a reference design is easy. It is just a program that is given to the manufacturing lines to make the boards.
All boards are made with data that is put in a machine to tell the machines where to etch traces etc. That is how you get asus and soyo motherboard being pirated, someone steals the files that hold the designs and just loads them into their own pcb machines. This isn't rocket science, the nvidia reference design files are probably just given to the manufacturers to use, and some just use them as is, and in theory it should be all great, but its not since the design has got to have a flaw somewhere making the 2d look like crap. As the arcitles about RFI filters have said, an RFI filter kills the video bandwith. A well designed RFI filter would do this very well, and thus kill the 2d even more since it would kill the video bandwith veryeffectively. A board with a shoddy RFI filter, would have more video bandwith since more RFI emissions would leak , and you would actually in theory get a better display with a crummy RFI filter.
Also manufacturer who make the reference boards, are usually creative labs or visiontek, and even those look like crap. The reference design is not right, hopefully the infusion of 3dfx talent there will fix it in future designs, especially should any of the gigapixel designed chips ever see the light of day . Even the old ati boards that were made by 3rd parties (some ragepro, rage 2 and rage128vr boards) looked better than most of the geforce2's out there
