I have an Intel i5 Quad Core 2.67GHz w/4GB RAM 2-SATA HDD's running Windows 7 x64 and both X1 and 8.5 in 32 and 64 bit mode.

It's almost identical to this one from Studio Cat ...

... and this one from Musicians Friend:

Besides its exceptional processor, the Rok Box i5 is also equipped with a 250GB primary drive, 500GB audio drive, and 500GB sample drive; 4GB of memory;

It's been suggested to me that an i5 with 4GB RAM such as mine and the ones being sold above by very reputable dealers are not capable of running 1 track with Guitar Rig Pro 4 on it in X1?

What are your system specs and can your DAW handle 1 track with Guitar Rig Pro 4 on it in X1C?

Specs

AMD Athlon II X2 2.81GHz
4 GB RAM
Generic 500 GB HD
GeForce GTX 560
Line 6 Pod Studio GX Soundcard
Windows 7 x64

2-5% CPU Usage with Guitar Rig LE

New Sandy Bridge per below.
No issues with GR4 in X1c.

That Studio Cat is a ripoff at $1050.. pretty much any mainstream PC manufacturer does better, cheaper.

FWIW, about 5wks ago for $800 I purchased an HP Elite 580T with i7-950, 8GB RAM, Blu-ray, 1.5T 7200rpm SATA 3G, GTX460, Win7/64.. and it flies.

HP Pavillion Q6600 @2.4GHZ, 4GB MEM, Nvidia 8400GS, M-Audio Delta 44.
Sonar X1c x64, Win7 HP x64.

Yes GR4 Pro runs fine @ 3-5% CPU in your test senario.

Just thought I'd eye pop ya. It's the development machine.
But it's runnin' X1 and a C compiler on my lap.

System 1:

Processor: Intel I3 540
Motherboard: Asus P7H55-M LE
Videocard: GeForce 8200 512Mb fanless
Memory: 8 Gb (2 banks 4Gb)
Sound Card: ESI Juli@ (for audio and MIDI)
HD: 500Gb SATA harddisk
OS: Windows 7 64 bit

System 2:

Processor: Intel I3-2100
Motherboard: Asus P8H67-M
Videocard: GeForce GTX 275 896Mb
Memory: 4 Gb (2 banks 2Gb)
Sound Card: M-Audio MobilePre USB
HD1: 750Gb SATA harddisk (high-speed)
HD2: 500Gb SATA harddisk
OS: Windows 7 64 bit

Both Videocard and processor have big low level noise fans. Both systems are self-build.

X1 (32 bit) is running smooth on both systems.

As a detail I can add on both computers there is a dedicated partition solely for music production. Those are not used for anything else! There is also a "game" partition and a Linux "daily work" partition on system 2. A few "software-test" partitions are made on both computers. Those are used for testing new software. On system 2 there is a "backup" partition, that can be used for permanent and temporary backup (using a high speed network for the second computer).

If you want more information, please ask... 

oops..double..

Grrr ... the nice make-up of my post is completely lost... Editing does not help a bit.

[Edit]
Well - after 3 times it succeeded.

I had to switch to Opera to do so.

I sure hope this is NO IE 9 "correction" (read: MS-destruction) of the forum software!
