although not entirelly nescessary for gaming, a cheap 030 acclerator with 8+ MB of fastram will help you A LOT. look for something like the M-TEC 1230/28 , they are cheap and very compatible. or get those el-cheapo 4/8MB fastram expansions...
but if u have more than 4MB installed with those cheap accels/memboards u will loose the pcmcia port functionality...
if u have the money, go for a Blizzard 1230 MKIV, they are great and don't disable the pcmcia port.
after you get that :-D , and register WHDLOAD too, u will need a bigger HD , it is very easy to fill 3-4GB with whdload games...
