I'm planning on putting together a system for mostly finite element analysis work, some CAD and Matlab (plus general office work).
So number crunching ability is basically top priority. I'd need decent graphics performance for the CAD stuff (but I'm not trying to squeeze every last fps out of Crysis) so not planing on blowing 100's on a graphics card. I'm also assuming that it's CPU that is going to be the limiting factor - I'm guessing a SSD won't speed things up much.
I also want decent multitasking performance as I tend to set an FEA job running and then try to continue to do office work on the PC.
Budget constraints have me looking at Socket 1156 processors (rather than 1366). Although an i7-920 system (of you can still find one) is about the same as an i7-860, the higher clock speed of the i7-860 should make it number crunch quicker.
The i5 has 4 cores, so this should give a pretty good FEA performance (for comparison, I'm currently running a Core2Duo E6420). Obviously the i7 has 4 cores and HT - I assume that the HT won't improve the FEA perfomance significantly, as hyperthreading would give you 8 threads, but each thread would only have half the resources compared to if I were running just 4 threads?
Am I right in thinking that the HT on the i7 would allow me to continue working (e.g. office applications) with a big 4-thread FE job running in the background whereas the i5 would "struggle" (though presumably still a world of improvement from my current system which is running 2 thread FE jobs).
An i7 860 system is looking at being around £100 more than an i5-760 system. I've read various processor reviews comparing i5-760, i7-860 and i7-920, and they generally say go for the i5-760 or go for an i7-920. However, from my understanding of the benefits I'd get from each feature, the i7-860 seems to be "right" for my set of applications?
Opinions anyone?
Or stick with the Core2Duo and wait for Sandybridge?
EDIT: The clock speeds of these two processors are the same...
