new build couple of questions

i have build myself a new computer and i have a couple of questions if someone could help

i have 4 gig or ocz ram i have been told i have to much i have build this computer for gameing and working with audio and video my question is have i got to much and why does it show up as 3.25gig

also the only thing from my old computer i used was to old maxtor hard drives so im looking to buy a new hard drive what would be the best type

windows media center 2005
motherboard lanparty ut rdx200
cpu amd athlon 64 fx-60 dual core
ram 4 1 gb sticks ocz Platinum dual core pc3200
graphics card sapphire radeon x1900xtx
sound card sound blaster x-fi xtreme music
psu hiper type -r series 580w
dvd burners 2 sony dru-810a

 

It only registers as 3.25 gigs because XP only supports that much, when Vista comes out it will support far more than that amount of RAM i believe.

ps. holy crap dude, thats like one of the nicest setups ive ever seen, musta cost u a fortune....

 

cheers viper it took about 3 months saving

is there someone that can give me some advice on what type of hard drive would be best for my system

 

My suggestion would be dual Western Digital Raptors in RAID 0. These are great HDD, and come in 36, 74, and 150 gig flavors. Personally, 148 gig is all i can ever imagine needing on a rig that is soley for gaming As an owner of said setup, i can attest to the fact that whenever playing BF2 i am ALWAYS the first person on the map! Pros? I always get the chopper! ;D Anyways, if ur not worried so much about speed u can always get 2 7200 RPM drives and RAID 0 them, which will be plenty fast, just not as fast as 2 10000 RPM raptors in RAID 0! MSRP of the 74 gig raptors is currently ~ 150 a piece (american). Good luck making your decision, and damn, nice rig!

XP supports 4GB of RAM, not 3.25.

 

Which is ultimately the problem. XP supports a total 4gb of physical memory and guess what? It counts your paging file into that equation
