I think the i5 is a good choice. The performance looks very stable in the review. If your config also has 16GB of RAM it may run warmer than their config, but it shouldn't be so much as to overwhelm the cooling system. I think HP automatically removes a configuration option if the lead time is over 30 days. Both Lenovo and Dell are showing 2+ weeks lead time on their i7 configurations as well. Hopefully Intel can get caught up with demand by summer.
