Ath II X4 640 vs X3 445 +unl

post #1 of 12
Thread Starter 
Hi

How many % of X3 are unlockable in your opinion(working core)?
How many % of X3 have L3 in your opinion?

Should I risk with X3 or choose sure X4?

Also, I need opinions on cheap mobo AsRock M3A770DE /AMD 770, DDR3 1333.
I really want to spend low $. Heard this mobo is quite good quality for low price.

Sorry if my question is dumm, Im new guy.

Thanks

Get X4... if you have extra $20 to spend... but usually the risk is worth it on X3.

If you are on a budget and hoping to unlock extra cores... why not get X2 555? It's between the price of the 2 you mentioned and will totally outperform those 2... if unlocked.

About the mobo.. I would say that's a good one for the money. It's cheap and has the acc feature that you need.

The 640 is fairly close with the 955 in terms of performance... L3 lack makes it a tad slower, not by much though. 5% on average. That mobo with try to unlock the x3 automaically, I think. If it's the same board I was reading about earlier.

Thanks...

Would you try to rate the success of X2 555 and X3 445 unlock?

Is there any better mobo in low budget to unlock?

Are you going to buy it on newegg? They have good deals on open boxes. Or check the Market Place on this site.

Im not from US. I will buy on my eBay. Is there any certain "thing" I have too look for with x2 555? A date on cpu or maybe question to seller?

Thanks

/e: If it fail to unlock x2 555 and will have to go on stock. How much slower it would be from X4 640?

I can see that you are really on a tight budget... Just gamble everything on 555 or 560. Anyway those cpu are still superb on gaming because of L3 and just cross your fingers for unlocked cores. Good Luck.

I know you're looking to buy on eBay... but before you do, consider this...

If the seller were trying to sell an X2 or X3, what are the chances that he would sell one at the X2 or X3 price, knowing that it unlocks to an X4?

Do you see what I'm saying?

It's more likely that they'll have tested their CPU to see if it unlocks. If they're selling it for a low price, they probably got one that's no good. If I got one that unlocked with all that goodness, I wouldn't be selling it at such a low price.
