Hi Rob and other system builders, In 2009 I built my own i7 920 and overclocked it to a very very stable 3900 megahertz. I have XP 64 bit on it.
In a Tradestation forums thread I posted a very detailed shopping list from Newegg of all the parts I used (more or less) and show that it can be done very cheap. In my opinion, the 920 version is (or at least was) the most affordable in terms of bang for your buck once overclocked. I had some problems getting things cool enough with all 8 virtual cores going, so I turned off the hyperthreading and just run with 4 cores. Attached is a PDF of my shopping list complete with colorful pictures of my i7 920 build during and after. FYI, I was going for lowest price rather than the very nicest stuff, though I did not skimp on mobo, power supply, CPU, or memory. The case, graphics card, and fans were not the best (or quietest). Hope this helps.

Basically I am running AB on a Mac Pro right now. 8GB Ram (ram is not one my constraints). I am running 2 x quad core Intel Xeon X5365 2.99 Ghz processors. I use AB for real time day trading... (not backtesting)... but I am pushing the core I run AB on to the max pretty much (My performance indicator in AB runs pretty consistently between 200 - 260%... I also have another 4 charts running on another instance of AB to utilise another core. Question is, in building a new system, what should I be looking for maximise AB performance....? Obviously I am looking at the i7 range of processors. However, given that I can only utilise one core per instance of AB (and I want to run as few instances of AB as possible), should I less concerned with going for more cores and more concerned with perhaps overclocking the cores I do have...? I could go the whole hog and overclock a Intel Core i7-980X Extreme Edition to 4Ghz... I don't know if that would be overkill given there would be a lot of processing power I couldn't access....? (although having 12Mb of onboard cache looks attractive since I could run larger DB's in AB more quickly). Any other critical issues I should be thinking of in terms of speed running AB...? Thanks for your time.
