Intel is preparing a wave of new server processors for the first half of 2012: 20 new CPUs in Q1 and another 20 new models in Q2, according to Digitimes.
There will be seven 8-core CPUs in the first quarter, including the Xeon E5-2690, two 6-core processors (Xeon E5-1660 and 1650) as well as three quad-core processors including the E5-2609 and dual-core processor E5-2637.
For Q2, Intel has apparently scheduled eleven Ivy Bridge H2-series CPUs and seven additional Xeon processors, including the Xeon E5-2470. There will also be several low-power models, including the eight-core Xeon E5-2650L and six-core E5-2630L, both of which will debut in Q1, as well as the Xeon E5-2450L and six-core E5-2430L in Q2.
Oddly enough a 2P gaming computer would probably hurt you more than it would help you. Inter-process latency, inter-processor latency and memory latency have a huge detrimental effect on real time applications that aren't extremely well threaded.
