my 1st linux gaming box

the suse installation went well yesterday, i'm a speed freak and I'm trying to compile the best uber tweak settings i can get on this OS.

will there be better performance gain if i use this setup?

/boot is on primary IDE harddrive ... lets say i'll alot 2GB of space on this one
swap is on primary IDE harddrive ... i'll alot all the remaining space...78GB.
/ i'll put this one at the sata drive with raid 0 ... i'll put all the 160GB dedicated for gaming and applications.

i found out that dedicating a separate harddrive for swap is the best option...is this true? or should i try to just use this settings?

any suggestions on this one? thanks in advance.
