Yes but sometimes not successful for all cores. Only buy a dual core if you are happy with that.

My 555BE unlocked all four coures but one was a dud and with tricore my overclock was more limited (got just over 4GHz) then when dual core (4.2GHz)

You might get a bonus of 3 or 4 cores or you might not.

If you want a 4 core then buy one. Athlon II X4 645 or a phenon II x4 955BE (a little outside your price range) good options.

I was the guy who needed the help lol so I will add that my price range is 110-120ish, which that 645 falls into.
The 645 you showed me compared to the phenom 2 920 here http://www.newegg.com/Product/Produc...scrollFullInfo doesnt have a 6mb L3 cache like the 920 has, is that an improvement for performance that you know of? they are the same price.... This is a tuff decision can someone make an educated choice and let me know what they think, thanks.

EDIT: Ok so I researched the L3 Cache and what it means myself. It handles instructions basicaly that the L1 or L2 either has or has yet to get when you make a request from a different core. I got the jist of it. So i would infact get a performance boost with the 920 over the 645, BUT the 920 has 3600Mhz HT and the 645 has 4000mhz, Would that make a serious impact that anyone knows of for performance?

I haven't seen any direct comparison but IMO the higher clocks of the Athlon II X4 should be of greater benefit.

I'll be overclocking it and cooling it with aftermarket cooling so I'm looking past the clocks.

heres some feedback quotes from newegg.
"You already know the pro's of this cpu, thats why your here. fast. fast. fast. very oc'able Im @ 4.2 on air."

"I dont get why people get 3.0 that is a bit more expensive when you can clock this to 3.5 with no problem with the stock heatsink."

"Even though this is not the black edition I was able to push this thing to 3.6 with ease."

Theres tons more, those are just a few.

EDIT: I still would like to know if 4000Mhz HT speed over 3600Mhz will make a big impact on performance. Thanks

Well TBH everything, Music studios, Gaming, Moddeling, texturing, Teraforming, modding for various different games. And I could do all that with just my 8800gt, BUT I got the GTX 460 for a reason, and that was to take it to the next level and learn new things the card has to offer for what I do. the bottom line is my CPU is horribly bottlenecking my GPU from what I hear and have found out my self by doing some OC'ing on my CPU and get more GPU usage out of the card. My CPU is as high stable OC as it's gonna get, its not enough tho, which is why I'm trying to get the right CPU for the money.

If modelling then obviously go Quad core.

HT speed won't make a big impact on performance. It's rarely saturated.

Northbridge speed makes a big difference, as does tightening down your timings on your RAM. Overclocking the HT-Link won't really improve performance, it rarely gets saturated as other have said.

For the applications you mentioned, definitely go with a Athlon II x4. The L3 cache doesn't make a HUGE difference (1-4 FPS depending on the game) as seen here:

http://www.tomshardware.com/reviews/...ache,2416.html

But the difference between a quad over a dual in the applications that can use it are huge. And while the Phenom II X2s have a chance of unlocking, it really isn't worth buying one in anticipation of a quad only to be disappointed.
