Mathematical processing

This is NOT a gaming rig. I am a geneticist and I do a lot of baysian analyses that take up massive amounts of processing power. Usually, we can send our big projects over to the on-campus cluster. However, some jobs can take a week or more on my 2.4GHz i5 macbook pro so I want to build a machine that has minimal graphics and high processing power to reduce the wait time (I included a graphics card so as to not draw from the processor if I am multitasking during a run). I need a basic machine with a huge processor so I went with a 4.0GHz i7 unlocked because I will probably try to push it into the 4.6-4.9 range. But as you can see the rest of the system is pretty minimal. On-campus we mostly use WiFi, and I would like to have a bluetooth connection; is there a wifi/bluetooth card out there that is not outrageously expensive (continuous internet connection is not essential)? Let me know what you guys think about this parts list... This will be my first build, precipitated by the log run times of these MCMC chains in programs like MIGRATE and MrBayes on my current computers. Please, any general comments are welcome.

Alright, so I have a few questions. Does the program you use use a lot of memory? Does it utilize hyper threading? Even if it doesn't you would still benefit with more cores unless it only uses one. If you want to try something more expensive use a server processor. This one http://pcpartpicker.com/part/intel-cpu-bx80635e52697v2 is a 12 core hyper threaded beast. You can get cheaper ones then that of course, that's just an extreme example. You could go with one of the 6 core hyper threaded ones as well which perform extremely well and would save you a lot of time.

Depends on the program. But yes, many allow for multiple threads, and plenty of memory. This link didn't lead me anywhere, but the price should stay around $1500.

Maybe like this?
