Need tech advice on abit kt7a raid board

[damnlimey]

I've just been given an abit kt7a raid board along with a 800mhz athlon .
Rather than spend hours or days searching the net for advice I thought I'd throw it
out to the techs at FR first.My questions are:

Is there an appreciable speed advantage to using the raid technology and 2 drives?(stripping?)
What video card should I get?
Are there any heatsink/fan choices that work better than others?(dual fans?)
What type of memory ,I know this board supports pc133 but is it DDR compatible.

Any other advice would be greatly appreciated,
Thanks.

Does anybody remember when 512 megs of ANY type RAM would have cost the same as a down payment on a car?

Oh Lordy! Yes! I'm trying to revive a 66 mHz 486 board to use as a backup web browser ( No. I am not kidding; it's the second best MB I have! ) and was recalling the first time I upgraded a Tandy 1000 SX (?) from 384K to a "full" 640K-- cost an arm & a leg, took forever to get the IC's ( remember the memory shortages we used to have? ), had to get a bootleg copy of DOS 3.3, etc., etc.!
