I have a 400Mhz Yikes! with the standard ATI Rage128. As I go to more LANparties, I'm finding the urge to get a better graphics accelerator, but the market seems limited for PCI cards. So my next alternative is to go AGP. To sum up all my rambling, where can i get a dual G4 AGP mobo with the processors or should i until apple releases its next system and search for that mobo? All i really want is to use a 4x AGP card, but i don't want to build a complete pc to do it. or would buying a new mobo not do the trick because of other incompatibilities (like for HD's, ethernet cards, RAM, etc.) i just want to swap the motherboards.

Hmmm - that sounds like a good plan ... there may be some minor hardware changes though that would affect the layout.

Here's a link that may help out: http://til.info.apple.com/techinfo.nsf/artnum/n58418

I have no idea where to find a new Sawtooth logic board, other than as an Apple service part.

To get one, you will either have to find someone parting out a system (maybe they stole one?), or find it on the parts grey market.

i just found an Inno3d GeForce2MX PCI video card. is it mac compatible? would the rom flashing trick work on it?

Search here http://www.xlr8yourmac.com/ . There has been some talk of flashing some PC version NVidia boards.

While it has been rumored that some GF2mx cards work with the Mac right out of the box (that is it has some kind of dual bios/firmware dealeo), I would say well away from the GF2 card. They are a nice series and nVidia has made some great gaming drivers for the card. The V5 is much better (PCI or AGP) and the RADEON is also much better. The GF2mx may run fast at low rez (because it has a fast GPU) but at high res (over 800x600, say) it bottlenecks (because its VRAM is slow as molassis in the dead cold of space - 3Kelivns). The Voodoo5 (or really an V3 or better) ROCKs for Glide games. Its 16bit is nearly as good as any other cards 32bit. Sometimes its just as good and FSAA really smoothing things out and makes it more 'realistic'. The 16bit for ATI (or just about any other card) sucks (but ATI is the WORST). Thank god the RADEON plays just as fast in 32bit as 16. In fact the RADEON is built for speed. Its 166MHz DDR vs. 200Mhz SDR for the MAC GF2-mx (I think the PC version use 166 or 183SDR) gives it about 66% more bandwidth. The hyperZ feature gives the RADEON an additional 10 to 20% bandwidth. The main issue I have with the RADEON is that does not have FSAA on the Mac (yet) and there are often issues when you try to get one ATI card to play nice with the RADEON (pci/AGP). ATI is still kicking so you have driver support form them (if you define support very loosely) and the card works well for RAVE (I havent tried OpenGL). If you want to go cheaper - check out the V5. Its a monster card with about the same bandwith (166SDR - but it has two banks - one per processor - so its about the same). You can get these for about $100, but there is NO SUPPORT. So do not expenect any driver updates and do not expect it to ever work with X, although it might. The reseller would probably give you 30 to 90 days to make sure it works properly...

AGP isnt all that. I've run in severl LAN parties... my PTPRO/G3 500 Voodoo5 with 256MB of RAM and a TON of HDs works as well as any of theirs. I would say it was on par with an 800Mhz PC system - depending on the card and config.

HTH, GL, YMMV
