It's a very similar rig to mine, I have the DFI Lanparty Ultra after a ropey experience with an Asus A7N8X Deluxe when trying to run a 200fsb CPU (Barton XP3200) with PC3200 Ram, after spending a lot of money exchanging the unbranded RAM for Crucial TwinX Pro (2x512 - and yes the second 512 makes a hell of a difference to performance) and having to underclock it I nailed the board as the problem
Anyway to cut a long story short, I am very happy with the DFI, good support in the form of a forum run by very technical guys and the bundle speaks for itself - only gripe I have is it lacks a game port... They reckon they are defunct, but I got an old Joypad that works a treat for certain games that I can't use
The MSI RX9800 was my latest addition - fantastic card. The VGA silencer is an absolute must because, although the stock cooling is excellent it was a damned annoying whiney fan that I could clearly hear. It was like having tinnitus!! You may want to pick up some ramsinks though.
