i was looking to upgrade my e6750 to a quad without upgrading my mb/ram as well.
I notice the 9400 has less cache, is that going to kill performance at all? Mostly gaming... I do plan on overclocking it, my current cpu has been at 3.6ghz for 2 years, and I'd like to keep it there.
Or would anybody recommend the 9550? if so why?
 
9550 all the way, but only if you can get one for the $170 Microcenter price. Of the two you listed I'd get the q6600 over the 9400 for overclocking purposes.
 
There are no microcenters around me. I did however find a q9450 on craigs for 165, so no tax. Does that sound like a deal? I cant find the price on a 9450 anywhere
 
Q9450 died an quick death. Great chip from what I hear though. There are a couple on ebay claiming NIB (which I seriously doubt, unless they've been in a closet/warehouse for a couple of years) for 235 and 375. A used one is currently at ~100. Also check prices on the X3350, that's the Xeon version of the 9450.
 
Alright, the q9450 deal fell through. I did find a 9400 on craigs though. Let me put it this way. q6600 vs q9400 both running at 3.6. Whats better?
 
They're about the same. The Q9400 will run cooler and a bit slower in some cache dependent games and apps. Pretty much a toss-up...I say get whichever is cheaper/find first for a good price.
 
Q9400 might be able to clock higher, but I'd take the extra cache (Q6600, Q9450, Q9550, et alia) every time. Shame the Q9450 didn't work out.
 
I wouldn't pay too much for a Q6600. People seem to charge quite a bit for a used one and as far as overclocking goes it's a craps shoot. Most of these chips don't clock like the early G0s. They also run much hotter than a q9400. Most of the benches that I have seen show the 45nm chips being a hair faster clock for clock while using less power. Keep in mind that it's really only a 1MB per die difference in cache between the two chips.
 
I've got Q6700 and a Q9450 and the Q9450 rocks. The Q6700 isn't bad but I'm sure the extra cache makes the difference. Not really a gamer here, mostly encode with both computers, but I can see more speed with the Q9450 in most apps.

Enjoy your new Quad.
