New PC for Pro Tools

[Jenre]

So I'm looking for a new PC before the VAT rate goes up..

I'm running Pro Tools M-Powered 8.0.4 with a Mackie Onyx 1220i interface. Checking out this setup from Inta-Audio.com. Looks good to me but i basically want other people's opinions because I don't know an awful lot about computers. This is gonna be used for tracking, composing and mixing..

ASUS P6X58D-E - X58 Chipset
INTEL i7 950 Quad 3.06Ghz
6Gb DDR III 1600Mhz i7 Triple Core Kit (Requires - Windows 7 64Bit OS)
Nvidia 8400GS 512Mb - Dual Head
1000GB SATA 7200RPM
600w Ultra Quiet Power Supply
Windows 7 64-bit
3 Port Firewire Card - Texas Instruments Chipset 1394a (TI Chipset)

£1,173.97 (inc VAT)


PT is currently only 32-bit, right? I've heard rumours Pro Tools will be going fully 64-bit soon, which might be announced at AES, so i'm planning on waiting after that before I buy. Maybe more RAM if so, though?

Any help would be great.. thanks in advance!
