Guyz with X2 5000+ Black.............

I'm planning to buy this cpu since current Phenoms have bugs...
But I'm going to pair it with an AM2+ mobo coz hoping for a drop-in upgrade when Phenom 45nm comes...

My brother has a Core 2 E4500...I've seen that it has good performance & the temp is really low..
How does the X2 5000 Black compare in perfromance & heat against the E4500...?

The fact that E4500 can be mild OC even using stock heatsink..does the X2 5000 Black can be OC using stock heatsink..??

The 5000+ BE doesn't have a stock heatsink, so you'll have to remember to add that as well.
If I was buying a CPU now, that would be what I'd go for
Will OC to 6400+ BE speeds, so plenty of bang for your buck!

Yeah, it's like $94 or something for the 5000+ BE while the 6400+ is almost $160 (It's nearly maxed on it's clocking potential too). So it's an awesome "bang for your buck" CPU as Lukebird said.

The thing E2xxx and 4xxx chips have going for them is their ability to use stock cooling while overclocking. (The increased L2 cache size isn't bad on the 4xxx either)

Anyways, just go with the 5000+ BE and be happy.

As others stated, you will need to buy an aftermarket cooler. No Heatsink on the Black Edition.

The E4500 and Even The E2160 are both faster than the BE 5000+ when all are reasonably OC'd.
XIBTLABS did tests showing an OC'd 6000+ losing to a Stock E6800 easily.
The OC'd E2160 beat that same E6800 in another.
This easily makes the E2160 faster than the 6000+.
The BE is not quite as fast as the 6000+ when both are OC'd due to it having less cache.

The E4500 is about 5% faster than the E2160 due to it having more cache.

While I'm waiting on an AM2 retention bracket for my Thermalright XP-120, I'm using the stock cooler from my old Athlon 64 3300+. I've got my BE in a new DFI LP UT 790FX-M2R, and Smartguardian (the DFI temp, voltage, and fan speed monitor) reads idle temps at stock frequency and voltage around 22-25 degrees C (how close those temps are to actual core temps is debatable) and ~37 degrees C under load. Increasing the multiplier to 15 for for a mild oc to 3.0 GHz puts temps at around 40-43 degrees C. Heat shouldn't be an issue as long as you've got any halfway decent aftermarket cooler and your trusty AS5.
