Strange cpu issues...


Hello hello,
I have recently built a computer that, I hoped, would be my primary music making machine. However, it doesn't seem to be able to handle as much as I would like. For example, 1 track in ableton with Native Instruments Guitar Rig running only reflektor as the effect tends to cause somewhere between 30-100% cpu usage and brings the system to its knees. The cpu meter tends to constantly "bounce" between low levels and very high levels. This is the case for all other audio programs as well.
I am running at 4410 with the proper asio drivers and with latency set to a reasonable amount.(Though I've tried all possible settings)
Here is whats in the computer:
  • GIGABYTE GA-790XTA-UD4 AM3 AMD 790X SATA 6Gb/s USB 3.0 ATX AMD Motherboard
  • AMD Phenom II X4 970 Black Edition Deneb 3.5GHz Socket AM3 125W Quad-Core Desktop Processor HDZ970FBGMBOX
  • CORSAIR XMS3 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 Desktop Memory Model CMX8GX3M2A1333C9
  • GIGABYTE GV-R545OC-512I Radeon HD 5450 (Cedar) 512MB 64-bit DDR3 PCI Express 2.1 x16 HDCP Ready Low Profile Video Card
  • Antec EarthWatts EA-500D Green 500W Power Supply

It also has 3 Seagate Barracuda 7200.12 ST3500418A 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drives.
  • 500 gb system drive
  • 1tb sample library drive
  • 1tb the drive audio is recorded to.

I am using a presonus firestudio as my audio interface.
Any insights?

Sure seems like a 3.5 GHz quad-core should be able to handle this, though I'm not that familiar with the NI guitar rig. Some reverbs can consume considerable resources but generally have a setting to adjust the resources required.
Do you have the OS configured to favor background tasks? If not, try that next.
