Xmaddness....so much of what you listed
A; isn't true
B: doesn't matter to me

AGP is a waste of my time and money....never need it never need to use it...pci is just enough for me to get by with for video busses....

I have plenty of AT boards with onboard PS/2 thank you very much...and alot of the other things you listed they don't usually have..

ATX does not make the system faster!!!! it is simply a power box with specs I don't like...ATX is just used with newer systems because it was invented around 1996-1997!!!! ATX IS IN NO WAY CONNECTED TO THE PROCESSOR EXCEPT FOR ENEGRY!!!

and as I said before...I don't care about silly little frilyl ammounts of speed that come from the length of the cable.....whoopdee doo I can have a slightly faster hard drive acess time.....that...It's amazing how much i don't care about that sort of thing..I have cooling covered....All of my cables are tube form for air flow concerns....everything else is just trivial...
It going to be an OLD game (descent 1 /2 *****Doom 1/2....Quake1/2....ect...and workstation....so little bits of speed I may pick up here or there that I am missing do not matter....


*****---maybe descent3 after I mod it to be all flat polygons...no more over work for mr.processor or captain video card ...
