if you have some loot get the Dell 2405 monitor....its AMAZING! and will do awesome res settings in games.
nothing seems bad at all....you went top of the line for everything....you are good to go.
What all do you have on your HDD's? if you have a lot of stuff you want to keep you could use a Raid5 card/array....its more expenseive because the card caosts around $600 but you will get performance higher then RAID0 in read/write and you will have the backup redundencey
Well I figure this one is going to have to last me for a bit so I might as well make sure it will.
As for the harddrives, right now I have an 80gig that I put windows on, along with various applications/games. Usually sits around 50 or gigs used. Second harddrive is a 300gig that has about 250 gigs on it. It's my fileshare drive, keep movies, videos, pictures, music, etc on it. With the extra space I was going to finish putting the rest of my dvd's into avi's on it. Along with iso's of my games.
