SB2 Installation Help

Hi All.I am planning an up-grade in a few weeks, just waiting for the new 9800 to come out,I can't remember exactly what I need to down load to get SB again,if I remember right I need two versions, one version then an up-graded one, I have had it for so long I forgot,LoLin case anyone is interested I'm moving up to the following specs.PS, is anyone on a high / fast system at the moment, I wondered how much better FS would be on a much faster machine.ie F/Rates etcASUS Enforce2 MB A7N8X Rev1.06.AMD Barton 3000+Seagate Baracuda 120 GiG Serial ATA HDD.1024MB Corsair Extreme Low Latency CAS 2 RAM.Vantec Stealth 520W PSU.NEW Herculese 9800Pro Graphics card 128MB.GF2 MMX 64MB Card.(I'm keeping this one for now as it's been a pretty good secindary card)4X Vantec Stealth Fans 120mm.Vantec Stealth CPU Cooler.Vantec Nexus Rehobus controller.Vantec Nexus Multipanel for keeping an eye on the temps and speeds etc and has another 2 USB & 2 Firewire ports built into it.I use 2 monitors and have been doing so for quite some time now and find it particularly usefull for FS, I use a 22" HP monitor in front of me for FSim and a 21" Dell just to the left of that for FS Nav, saves constantly switching screens and they are getting very cheap now as everyone seems to want the waifer thin panels,so it'a a buyers market for us now. plus it's very usefull for installing things as well,you can have the readme open on the left monitor while watching / installing on the main monitor,and it's good for web browsing too as any other windows that come with a site go to the left monitor.
