yes to the rig in my sig. I would save the extra even for the i3 series over a FX4100. Im building a rig for my eldest kid and rather than be cheap and go AMD, i'm going to be going Intel and wait the extra bit to get her rig up and running. Intel atm IMO has more going for them and building an IB or SB rig will last longer than a current Bulldozer CPU.
I feel its a fair comparison beacuse both quad cores are marketed towards mainstream users. I had a budget of $400 and came up with the CPU/Mobo/Ram combo in my sig. Could I have gotten more cores and a better board if I went AMD? possibly, but after reading the Tom's $200 CPU roundup, I decided a an i5 2400 was the best choice.
