I bought a stock I5 model on Black Friday. I now see that I can get a veterans discount on a BTO I7 for 10% off normal price. I can get an I7/8GB/256GB for $1169 + tax instead of the $1099 for the I5/8GB/256GB + tax normal price. Do you think the upgrade in CPU is worth the hassle to returning it then ordering a new BTO model?
