FX-4100, what to expect?

I recently got a bit of money and went with an FX-4100 and this budget motherboard: http://uk.asus.com/Motherboards/AMD_AM3Plus/M5A78LM_LX/
with 8gb XMS3.
I realize bulldozer isn't a great buy and the four core is.. well I don't want to think about it, not to mention the 3+1 phase power of the motherboard, but I got both for £100 brand new which is the price for a new 955 by itself so I couldn't really say no.

My main question is, what should I expect coming from a Core 2 duo E8200? I have a H60 (in push/pull) and will overclock it and see what I get but I'm a little worried I'll barely get an upgrade from my present E8200, this is mostly for games (paired with a 6870) and even though I've heard it's not a 'true' quad core I feel it should perform better than my mature dual core.

Any replies are appreciated, thankyou.

I think you're going to be disappointed because while it theoretically has 4 cores, I hear these 4 cores probably won't have the same "strength" as real cores (80% I believe. It seems to have the drawbacks of hyperthreading essentially) and it has lower IPC than Phenom. With a budget motherboard, you won't be able to overclock it to the moon like most people do. Not sure what to say, but I think you would have been better off with the Core 2 Duo.

Surely my core 2 duo isn't better, from the reviews I've seen so far (stock) the 4100 does better than the 6100 in areas, I'm not saying it's great but my core 2 duo is almost four years old.

Well I wouldn't say the Core 2 Duo is better, but I think the performance jump might have not been big enough to justify an "upgrade". Just wondering, did you overclock your Core 2 Duo setup? Those things overclock like beasts. I had a Core 2 Duo E8400 on an "average motherboard" clock at 4.5 GHz on basic air cooling.

EDIT: I'd also like to add that if you had gotten a better motherboard, I think the upgrade would have been worth it. Would allow you to OC the FX-4100 but also possibly get a better FX processor in the future.
 
It should definitely be faster. Regardless of how "real" a quad-core the FX-4100 is, the extra threads should speed up modern games and make multitasking smoother.


I'd be interested in any benches you run, though. As well as how high an OC you manage to get (if you end up doing that).
 
I was hoping this to be more of a stepping stone until 2011 or better, and I could not overclock the E8200 at all due to having a P31 motherboard and they never fixed a PCIE bus issue so it was almost impossible past 2.8ghz.

Ohh alright. Then this is definitely an upgrade....
 
The 4100 is going to have to clock at 4.5 to match single threaded performance of a core 2 at 4.0. Sad but true.
 
The FX4100 has an new AMD integrated memory controller while the E8200 has the FSB (huge plus factor), supports virtualization while the 8200 doesnt, has all the extensions plus future ones while the E8200 supports half of them and it resides on a fresh platform with new AMD x86 cores coming in AM3+, i say let the Core 2 chip find a new owner.
