I7 vs i5 and some DPI questions

I'm helping my friend complete his build (We've been working on it for a couple months) all he needs now is a cpu. his mobo is the intel sabertooth 1155 whatever, (I'm not fond of sabertooth, but whatever it looks baller) and we dunno what to get. He's not upposed to the extra money it takes for an i7. i7 2600k is only 279.99 on newegg (pretty solid price imo) and the i5 2500k is only 160$ @ microcenter, so that'd be a great deal, too. He's super into overclocking and stuff, where as I'm not really, so we were thinking mebbe the older cpu's would be better since the new Ivy's get hot. (He has an H100i) so which one should we get? I'm thinking the 2500k, but I'm cool with loaning him the cash for that i7 if it's gonna be worth it at all (He does render down videos alot, would th i7 help with that?)

Also a personal question while I'm here, my new gaming mouse arrived day before yesterday (Mionix NAOS 3200) (Loooveeee the damn thing. this >G700/Mamba/Deathadder/G500) And I'm not sure what DPI to run with, or what difference it makes. My old mouse I've used the longest only has 800dpi, so I'm kinda used to that, but now I've been running 1600 for a couple days (My mouse does 800, 1600, and 3200, 3200 was just a bit too much for me) and this feels nice.. but, like, is it anything other than sensitivity? Would it be best for me to crank up the dpi to 3200 then just lower my sens? would that provide better accuracy or would I just be stupid. Also what's pulling rate? (Software says 125hz, 250hz, 500hz, and 1000hz) Idk. Thanks a mil

Why not go for an ivy instead...Performance better/Power Draw is less...The i5-3570K is well priced and will give you alot of bang-for-buck in an unlocked CPU...

There are many DPI explanations on the web. Google is your friend. Besides it being in the wrong thread...

Because the 2500-2600-2700 are like 100$ off. lol. and almost the exact same performance. I'd take a 2700k for 219> a 3570k for 219.

Yeah, you'd be much better off to get Ivy Bridge, but if you friend is really, really, REALLY into overclocking, then that's where I'd recommend the i5 2500k, as it isn't a stove when you add voltage to it.

And DPI stands for Dots Per Inch, so if that old mouse was at 800 DPI, after you move the mouse 1/800th of an inch, that registers as 1 pixel moved. Not exactly the same as sensitivity, but a higher DPI does make it more sensitive. I run 2000 DPI normally, but when I'm in ArmA II, I usually set it down to 800 DPI.

If you're OC'ing above say 4.5GHz then aye - sandy bridge benefits as far as heat goes.

In the mid-4GHz range, Ivy Bridge will afford you 4% to 7% better IPC than Sandy Bridge. But you can overclock further Sandy Bridge for better performance.

SB will not be better performance because IB is better ipc. SB will oc higher but a lower speed of IB will be able to match the performance. Meaning whichever you get, you will get similar performance. The only difference would be heat and power. IB would be more heat but SB would use more power.

Dpi is not necessarily linked to how many pixels move. The dpi is the image resolution the mouse sees, sensitivity can be changed.
