Not to sound too pius about it, but the DnetC, MilkyWay@Home and Collatz projects aren\'t my cup of tea; - I ran Dnet for 3+ years and only stopped because I feel my CPU time is better served helping humanity find cures to Cancer and diseases than cracking cryptography (hence going for Rosetta).

But thank you for informing me that there are projects out there to use the ATI cards! - Will have to keep my eye out for worthwhile projects when they become available for the ATI technology.

Hi P.P.L

Specs are:

Gigabyte GA-890XA-UD3 AM3 motherboard
2x 2GB DDR3-1333 A-Data RAM modules
Gigabyte built ATI-HD5770 video card
1TB Western Digital Black Edition

Currently using stock standard cooler fan, and to be shortly replaced as Rosetta powering through the CPU makes it work rather hard.

I\'ve read about the overclockability and find that power consumption goes up quite significantly for an extra ~500mhz.

Unfortunately with the ATI card it won\'t crunch work units, however I picked this due to the price/performance ratio against the Geforce 260 based cards - Lower power consumption and better FPS in games when they occasionally get played.

Up and running now;

Whetstone 2318 per CPU
Dhrystone 8503 per CPU

Against the old Core2-E8400 of 3040/8760 per CPU

So technically slower than my old rig, just so happens to counterbalance with more cores.

Oh, and its Win7 Ultimate x64 w/ 4GB DDR3

Thanks folks for your input; Have picked up the 1055T this morning and just about to start the due process of putting it together!

It\'d be nice to simply insert more cash into the equation (not withstanding my idea of a server farm for BOINC when I win the lottery); However the 1090T is in (NZ Dollars) $150 more than the 1055 - Coming in at $NZ505; And that is wholesale pricing.

With the tight budget for this, I can only go either to the 1055T or the i5-750; However it appears I\'ll be leaning on the 1055T as other benchmarks I\'ve read put the 1055T ahead of the 750. (

With the other application of the build being the occasional game, GPU takes care of the performance anyways!

Bit sad, seeing as when I purchased my C2D-E8400 it was streets ahead of the AMD offerings. Now the tables have turned again!

Thats what I was thinking - The more cores the merrier - However if the Intel chip can outperform the PhenomII on 4 Cores against 6 then it\'d make sense to stay with Intel. Hence the query about performance :)

Hi guys,

Just about to do a little PC upgrading, and one of the biggest decisions I have to make is which CPU to go for. Of course being a home family PC it\'ll be used for a spot of gaming and the likes, but to be honest the main reason is to crunch more workunits!!!

PhenomII x6 1055T or Core I5-750
6GB DDR3 (will be on either choice)

Currently running a Core2Duo E8400;
3040 MIPS (whetstone) & 8760 MIPS (dhrystone) per CPU

I know there\'ll be a bit of variation dependant on motherboard choice, RAM, etc, however I\'d like to hear from anybody that has either of these CPU\'s to post their CPU benchmarks from Rosetta.

Thanks in advance!
