Should I spend 20 euros more on a X5670, instead of a X5650

I have come across a rare occurance in Romania. A LGA 1366 Xeon, a 6 core one at that. I ringed up the dude and he said he had about 5 6 core Xeons, 3 X5650, a X5670 and a X5690. He offered me the X5650 for 350 lei and the X5670 for 450 lei.

My question is, does the X5670 overclock higher due to the larger multiplier? I found out my motherboard doesn't like going over 210BCLK very much (4GHZ on my current i7-920). Would you think it would be worth it for me to spend more? The guy said he will test how far each one will overclock on the same motherboard that I have, as he has a few of those (Gigabyte GA-X58A-UD7), if the X5670 turns out to overclock higher, should I spend more on that instead of the 5650?

No it's not worth it.

I didn't test that specific CPU, but I fooled around with a lot of the x58 xeon CPUs and came to the conclusion that the higher models really aren't worth it. The OC and thermals will be about the same.

The 5640 and x5650 are the best ones from my experience.

I had an e5620 that I bought for all of $8 that I pushed to 4ghz. I kind of wish I had gone further just to really test it, but I didn't.

EDIT:

I have an x5650 @ 185 BCLK atm.

The X5650 will easily do 200 bclk, whereas the X5670 is more thermally constrained. I did manage 197bclk with X5670 but my cooling (a decent air cooler) would not keep it cool enough for continuous heavy work loads.

Thanks for the tips, I'll be going for the 5650.
