Help building a PC for statistical research


I am a self-confessed computer idiot, so was hoping that some of you may be able to give me some guidance in purchasing a new PC to be used primarily for doing statistical research. Essentially, my work has me accessing many (up to a few thousand) small files (avg size between 5-25MB each) over and over and running calculations on them.

Based on what little I know, I'm guessing that an SSD drive will be useful...and because I often work with the same dataset repeatedly after initially accessing the files, a lot of RAM will be helpful as well. Since the total size of my database is ~55GB and the OS taking up about ~25GB, I was thinking that I'll need an SSD that is at least 100GB (leaving a little room for growth). The largest dataset that I will be testing on at any given time is around ~22GB, so I was aiming for 24GB of RAM.

Other than that, I won't be doing much on the machine while doing this work other than web surfing and maybe listening to Itunes. For now at least, I only need a single monitor. Including the OS and monitor, I am hoping to get it built for under 2500.

Since I know so little about computers, I don't think I'm comfortable building one myself, so I've been looking through custom PC builder websites. Below are two configs (w/o monitors but w/OS) that seem to address my above goals, but I have no idea if everything is compatible, will overheat, or has crap/unnecessary parts. If anyone has thoughts on any of this, it would be greatly appreciated.

Oh, forgot to mention that I'm a little wary of purchasing from cyberpower based on what I've read about them...but they do seem to have the best prices.

  1. Thanks for the input gkay. Question, any idea why the same memory purchased in 6 X 4GB cost considerably more than twice the 3 x 4GB that you posted? $750 vs. $560 total for two 3 x 4GB??
  2. ^ Well it is most probably because it probably comes in the single package...apart from that I dont see any other reason...
    You can buy 6 single 4GB sticks and run them in Tri-Channel with no issues...The only thing you have to see to is that they are all operating at same speed/ timings and preferably same operating voltage and same company if possible...
