System Hardware

Presentation was designed to work well with generic PC hardware. Hardware requirements really depend on the experiment. Some experiments may run acceptably even on very old systems. Other experiments may require a lot of RAM or a current video card. In addition, some hardware may not work correctly because the drivers for that hardware do not correctly implement the interfaces Presentation requires.

The following recommendations may be helpful if you are purchasing a new system to be used primarily with Presentation. These are not minimum requirements. Also, please read the notes below for each item.

Sample Basic Presentation System

• CPU: Intel Core i5
• Motherboard/brand: See notes below.
• RAM: 4GB
• Hard Drive: 7200RPM SATA2
• Sound Card: Sound Blaster Audigy Rx recommended, but most audio cards should work for most situations.
• Video Card: Any recent GeForce, Radeon or even CPU-based graphics

Sample Presentation System for High-Res Video

• CPU: Intel Core i7 (quad-core preferred)
• Motherboard/brand: See notes below.
• RAM: 6GB
• Hard Drive: SSD SATA2
• Sound Card: Depends on timing requirements. We've tested the Sound Blaster Audigy Rx.
• Video Card:
• 1080p at 30hz video: any GeForce or Radeon on PCI Express 3.0 x16. Late gen desktop Core i7 quad-core graphics should work.
• Higher than 1080p and/or greater than 30hz video: any late gen GeForce GTX or Radeon R9 on PCI Express 3.0 x16 should work.

CPU
Obviously performance will increase with the speed of the CPU. The best price to performance ratio is usually at the 3rd or 4th fastest CPU clock speed available. Multi-core CPU's such as the Core2 Duo and Core2 Quad are recommended because certain features (such as streaming video) can benefit from having multiple CPU cores.

Motherboard/brand: The motherboard used will need to match the processor and RAM that you get. Most new motherboards support SATA hard drives (recommended). We recommend that you have your vendor make those selections and assemble the components. It is usually a good idea to also have the vendor install the operating system and drivers. If you need fast hard drive access, you could try for an SATA RAID setup, supported by the motherboard. The motherboard should have a PCI-Express 2.0 x16 slot. Some better known manufacturers are EVGA, Intel, ASUS, A-bit, GIGABYTE and MSI.

RAM: The amount of memory required for an experiment depends on the size and number of stimuli that you are using. Having extra memory never hurts and it is relatively cheap. We recommend getting 6GB if you can afford it, and no less than 4GB.

Hard Drive: For video playback, an SSD drive is recommended. If not playing video, a 7200RPM SATA2 (3Gb/s) drive will work fine. 5400RPM may be slow if you plan to play video. A 10,000RPM SATA2 hard drive can work for high-res video, but most 10,000RPM drives have a high pitched whine. The Seagate Barracuda series of hard drives offer quiet, reliable and fast performance. You could also try an SATA2 RAID configuration (multiple drives acting as one). However, if you can afford it, SSD is really the way to go.

Operating System: You should be able to achieve good performance on any of the supported Windows operating systems, but Windows 7 has better support for low-latency audio. We no longer express a preference for a 32-bit OS vs. a 64-bit OS. Hardware manufacturers have caught up and nearly all have good 64-bit drivers. Presentation is a 32-bit application and does not benefit much from a 64-bit OS. We do not have a time estimate for fully 64-bit versions of Presentation. On any system, you should make use of uncertainty reduction techniques. See the benchmark feature and the Optimizing Your OS tab for more information.
