Thread: Which one CPU i Choose 920,860,or i5 750?

A couple of months ago, I was really close to buying a build with an i7 920 and was ready to buy and then something possessed me and just decided to hold off because I knew something new cool would come like the i9's i5's, a new socket, and new i7s also. Therefore I wanted to clarify a couple of things. For a new build that I will be redoing and buying within the near future.maybe during thanksgiving I am not sure, I want to know the main difference and benefit between these three CPU's
Intel Core i7 920
Intel Core i7 860
Intel Core i5 750

It seems like all have their pros and cons and its really weird how they are similar but different. A core 920 is 2.66 GHz while a core 860 is 2.8 GHz however a core 920 is tri-channel ram support while the other is dual channel, also they are different sockets, and 920 uses QPI and 860 uses DMI (I don’t even know what DMI is and how it compares to QPI). Also the core i5 is the same clock speed as an i7...but has dual channeled ram and a different socket as well as DMI also. Therefore all these processors seem the compete. I am probably not getting an i5 anyway but and 860 and 920 seem awfully similar. I was wondering with their pros and cons which one would benefit me most? Taking into account the QPIvsDMI, tri-channeled vs. dual channeled, socket 1366 vs. 1156. Here is my use of my computer and what i need it for so you can determine which processor is better for me: (BTW price does not matter since its like difference.)

OS: Will be windows 7 64bit and might put another OS on it like Linux or xp.
Programs used:
-Nero ultra edition, burning CD's...etc
-Audio and Video File conversion
-Photo shopping a little
-Visual Studio Professional
-Microsoft office 2007.
-Background Processes:
-firewall
-anti-virus
-realtime disk defragmenter Disk keeper
-NVIDIA video driver

(BTW I would like the processor that would give me the fastest virus scans assuming they are the only variables if possible)

Thank for any help. I am open for both CPU suggestions. I am torn between the two. Tell me which will suit my needs better.

I believe the i7 860 will be better in performance since it's 2.8 GHz and also has the new turbo mod. What are confusing me are the new LGA 1156 Motherboards, with dual ram. People say LGA 1366 boards are better for future upgrades but we never know what socket will be the future cpus and stuff. Also both seem to over clock easily.

This isn't helping you but that's what I'm concerned.
