## Build a new machine

For now the most affordable solution for this is probably a PC with a good GPU. Try this configuration which is reasonably powerful, have no bottleneck and reasonably affordable (small form factor machine):

• Gigabyte GA-B85N-Phoenix mini-ITX motherboard
• Kingston KVR DDR3-1600 RAM 8GBx2
• AMD Radeon R9 290X GPU (or if you can afford it, R9 295X2)
• Kingston SSDNow V300 120GB SATA-6Gbps SSD

Or if you have a good gaming rig, use it. The machine listed above is actually a suggested SFF gaming rig.

Another rig, a hell lot more expensive, a hell lot larger, more than three times as fast as the previous rig, and still no bottleneck at all:

• Two Intel Xeon E5-2643v3 processor (3.4GHz hexa-core with hyperthreading)
• Asus Z10PE-D16 WS dual-socket motherboard
• Kingston KVR DDR4-2133 ECC RAM 16GBx8 (or if you can afford it, 16GBx16)
• Two AMD Radeon R9 295X2 cards in CrossFire configuration (4 GPUs total, and if you can manage it, get three of them)
• Intel SSD 730 Series (PCIe NVMe card)

## The single-machine supercomputer

If you can score a Sony PlayStation 3 that can still run Linux, that beast will be able to help you a lot. By the way, according to USAF, put 1790 of them together in a Beowulf cluster and you get a TOP500 listed supercomputer.
