I am a junior in highschool right now an am going to be going into a four year university for engineering. I am also big on flight sims and gaming in general. I want to be able to keep this processor until the end of college. Would the I5-750 be sufficient or is it worth it to get the 920? Is there really that big of a difference between the two?

For gaming you're better off sticking to i5. Hyperthreading (i7s only perk over i5, not including x58 chipset perks) doesn't help in games.

You should price systems going either way and see what the difference is. When I was contemplating some new CAD workstations about 5 months ago I compared prices and an i7 machine would cost me about $300 more than an i5, for very little positive benefit. At the time the CPU was $90 more, the ram was about $100 more, and the motherboards I selected were about $100 more. At this time the motherboard prices are closer, the ram pricing will depend on what configuration you need, and chip prices are still about the same.

As I understand it most i7 motherboards use triple channel memory so you can have ram in multiples of 3GB whereas i5 boards use ram in multiples of 2GB. If 3GB is not enough for you but 4GB is, then you pay a penalty with the i7.

If you are a Junior and you want to use the machine for 5 years, that might be pushing it. Most Engineering schools don't get you into anything intense for the first 1 or 2 years anyway, in which case you could get by with just an ordinary laptop or desktop until then. When the time comes when you need the supercomputer, you can build it then.

You don't go to engioneering school to play games. The i7-930 is the choice for engineering school .... and will serve darn well in your free time for gaming. In my engineering office, we get a god 4 years out of a laptop. Mine will be 4 years in June and AutoCAD 2011 isn't giving it any trouble at all.
