You've put all that effort in Adam, you should probably not go for a new pc, but grab a new motherboard + cpu. (probably should have done it before the ram
) RDRAM, never heard of it. Was that before SD?
You can grab a motherboard + decent cpu package here in australia for like $350.
which is like, what... $280 US
2GB DDR RAM - $500 AU
which is like, what... $400 US
so, if those calcs are right.. instead of getting that ram, you could have upgraded your pc with a new motherboard, decent cpu + same amount of proper, faster, better ram.
Just dont think about it like that, Merry Christmas.
