Well I'd say if you need to save up then maybe look towards these in dual core LGA2011. It will be almost a year before they are out, so maybe not for right now... :-)

Something to look forward to.

I have to reply Kirk as have personal experience of these on the sr2 under ubuntu folding bigadv. You can run them at 196mhz fsb fully stable which nets 3136mhz using the 16x base multi. You can get 17x on all cores which gives 3332mhz but you have to boost the voltage up to 1.28v to boot ubuntu due to the os using high turbo multis. To cut a long story short using a gold rated psu at 3136mhz the rig consumes 310w at the plug and produces 135k ppd so not e5 xeon territory but not that far off.

Cheers for that Ben

Atm I'm getting 90k ppd so a worthy boost but I thought the E5's are netting 300k+ ?

They are, the CPU's are the same price (ish) but a new mobo would set you back close to 500.

E5s are not netting 300k ppd+ in general.

2 x E5s at 2.5ghz will net you 180k ppd in the real world.

It all depends on clock speed - some 3ghz chips could net you 250k ppd+

But have you seen the price of the faster e5s - even es on ebay ?

P.S. sent you a p.m.

Ah, yes - I've fantasised about having 4 of these, but am still waiting for motherboard prices to drop.

And you would probably have to pay the VAT at 20%.
