So, I was all ready to order my shiny new i5 4690 3.5 GHz with 16Gb RAM to replace my 7 year old Core 2 Quad with 4Gb. Then I did a wee test... My dev PC runs Linux Mint but I also have an iMac for video editing etc, specs: 2.8 GHz Intel Core i7 (mid 2011) 8 GB 1333 MHz DDR3 I use eclipse for development so was able to set up the same environment on both machines. Guess what. The old Core 2 Quad compiled my projects faster than the i7! I have solid state drives in both machines. So, to any hardware buffs out there, would I really experience a big difference on my dev machine by upgrading to a new i5? My unscientific test seems to suggest it might not really be worth it, though it seems really hard to believe. I had expected a CPU intensive task like compiling to receive a big shot in the arm with the i7, but for it to actually take longer puzzles me to say the least!
