When you need one. No matter how long you wait, there will always be another chipset coming out, or a lower price. A week after you lay your money down, so it seems. Get off the treadmill. I tend to buy as good a machine as I can afford and then hold that machine for many years. I use this same philosophy for buying cars, I've owned both a SAAB and a Mercedes for 14 years each - two cars, 28 years - not bad at all. A Lenovo T410 bought in 2010 is still quite usable. I have only upgraded the storage from 500gig to 2 terabytes, and have repaired the keyboard over those twelve years or so. It's now my 'spare'. I bought a P53 with 5 terabytes of SSD and a 4K display as its replacement two years ago.
