That one costs the most by the way. one moment
Well if you're asking between the 3, I figured you weren't concerned with cost.
The only difference between #1 and #2 is the CPU, which is better in #1, so you can eliminate #2 entirely.
Between #1 and #3, #1 has the best CPU, the most RAM, and largest hard drive. Those three are enough to outweigh the faster hard drive in #3 if you ask me.
