Windows 7: intel i5 or i7

Google "advantages of hyper-threading" and see if the reasons apply to you. The i5 lacks hyper-threading. If my applications could take advantage of hyper-threading, I'd go with i7 in your situation unless budget was a major consideration.

On the other hand, you may do something that can take advantage of hyper-threading only 2 hours a month--in which case maybe it isn't worth the premium. At 2 hours a day or 2 hours a week, maybe it is worthwhile. Purely a personal decision.

re hyperthreading - I did a Cinebench test on an old i7 930 (8GB 3.8GHz) with HT on and off recently. The results surprised me. I found HT only gave about 26% boost (I expected more). Results were 6.47 and 5.13 respectively. I know most people don't use Cinema 4D, but Cinebench is considered a good benchmark for video render software that uses all threads. See snip (cpu would show all cores @ 100% during render test) - your mileage may vary, as they say

I always check in Resource Monitor > CPU tab. The graphs on the right side show you very well which cores are busy.

A top I5 will still do the job greatly...Whichever is cheaper, And most cost effective then go for that one!

I agree, unless you want to encode videos day and night. There the i7 really makes a difference.

I have made a test encoding a video on my i5 (laptop) versus my i7 (desktop). There is a significant difference. It should be said though that a top desktop i5 would be faster than my laptop i5.

Also got to remember that a top I5 Will be better than some of the i7's as well.

A 26% boost is still significant, though. That cuts every minute of rendering down to 44 seconds.

if you are like any normal person, you may wish you got the I7. in my experience, I sometimes opt for the practical and I regret not getting the faster hardware. sounds like you're gonna do the install. if so, what thermal paste you gonna use? anyway...keep us posted
