My New PC...

Hey guys, i have already posted a system spec but as the komplett site is currently playing up i haven't ordered this pc yet...

Just wondering if anyone has any more suggestions about the spec as i'm spending alot of money (£1500) and want to get it right 1st time :)

* AMD Athlon 64 X2 4400+ 2.2GHz Socket939, 2MB, BOXED w/fan
* NEC DVD±RW burner, ND-4551A, 16x,Dual, Ram, LabelFlash, Black OEM
* Thermaltake Blue Orb II CPU Cooler,Blue Light, 17dBA Socket 775/754/939/940
* Thermaltake Silent Purepower 680W, DualFan, 4xSATA, ATX/EPS, SLI, 20/24pin
* Thermaltake Xaser Tsunami BlackAluminum with Window (Without PSU)
* XFX GeForce 7800GTX 256MB GDDR3 eXtreme,475MHz, PCI-Express,Dual-DVI/ViVo,Retail
* AKASA cold cathode case light, U-violet,Dual pack, on/off switch
* DFI LANPARTY UT nF4 SLI-DR Expert, FW,nForce4 SLI, Socket-939, GbLAN, PCI-Ex16
* OCZ Platinum PC3200 2048MB Dual Kitw/two PC3200 1024MB DIMM`s, CL 2-3-2-5
* Western Digital Raptor 74GB SATA8MB 10000RPM
* Nexus DiskTwin, Stops HDD Vibration andResonance, Fits in 5.25" bay, Black

I will be using the PC for gaming as well as general computing (i.e. video encoding, music production etc.) and as a media center...
Things i will upgrade later:
GFX card for SLI,
Soundblaster X-Fi,
More storage.
Lemme know what you think.

I agree. The Raptor will be great for the OS and maybe game installations, but you should get a storage drive for things that don't need the speed of the Raptor.

Ok, hard drive space isn't too much of a problem as i've got some old IDE drives to use for the moment until I upgrade them to some nice SATA drives.

Another question, which OS should i install, XP Pro SP2 or XP x64?
I don't know how much of a performance boost x64 will give and i'm worried about having software/driver compatibilty problems, especially when i want to dabble in overclocking ;)

I think you would find that XP x64 isn't really ready for primetime... XP SP2 is (by M$ standards) pretty stable and drivers are consistently available for it.
