For Seti, GPUs rule for processing. If running projects that can only use a CPU, then the CPU matters.
With CPU crunching, running more CPU cores will result in better throughput per hour than less cores at a slightly higher frequency; and it allows you to maintain similar CPU processing throughput to a CPU with less cores, even if 2 or more are reserved to help with AP GPU processing.

to get more than an 18% performance increase you would need to overclock which would demand more power and cooling. But $800 could go to gpus as well.

Thanks Grant & Woohoo for your answers. I am thinking of going with the 8 core. Something dawned on me about my Samsung Evo SSD. How much space is reserved by the system on a 500 gig drive? I know its around 69 GB for a standard Western Digital Black edition 7200 rpm Leaving you with approximately 931 GB

---

The amount of space reserved by the system varies depending on the size of the drive & the amount of RAM installed.
I've got 120GB SSDs (115GB actual usable space) and the system drive has over 30GB free space still on it.

Thanks Grant. That is a substantial amount of hard drive to be taken up by system resources. I am going to go with the 500 GB SSD and 16 gig of the Corsair 2800 MHz RAM. Out of complete interest have you set Boinc up so the main program is on a standard hard drive and the data directory is on your SSD?

That's not just system resources, it's the OS, programmes, data etc.
The Windows directory itself is only 30GB in size.

No mechanical HDDs in my system, just 2 SSDs.

I'm with you. I think you may have slightly misunderstood my question. What I was meaning is how much space is available on the SSD before you installed anything? I'm assuming for a 500 GB drive it wouldn't be 500 GB that you can use

Why not? Are you confusing base 10 numbers used by drive manufacturers and binary numbers given by the OS to mean there is different usable capacities?

My 120GB SSD's show up as 119GB usable if that helps.

Cheers.

I would expect it has 500,000,000,000 bytes to use, or 465 gibibytes if you prefer.

Thank you your information and is very helpful.

Thank you for this information. It is all always interesting to see how much hard drive is actually taken up before you put anything on it. It would be nice if drives actually stated how much usable space instead of the actual size of of the drive. I know that will not happen

They're stating the same thing. You have 500GB usable space in decimal, or 465GB usable space in binary. Both numbers are correct and both numbers show usable space, they simply state that space in different ways.

No space is being "taken up" as you stated. It is more that the storage industry uses a different standard than the ones used for other measures of capacity in a computer. The good thing about standards is that there are so many to choose from.
If you want to quickly convert from GB to GiB you can just divide by 1.074 or use 1.1 for TB to TiB.

Yes you are you are right they are stating the same things just in different ways

Speedy might have wanted to know not how many addressable bytes the disk provides but how many bytes are available for the end user. Some small amount is used to partition the drive. And then file system uses some amount of the disk space for itself. How much depends on the file system type and the size of the disk (or partition).

Thank you this was the exact information that I was after. I now know the answer. It seems it is very dependent on the size of the hard drive

No, he was definitely confused over binary vs. decimal. He wasn't asking about file system and partition usage. You could tell by the questions he was asking that he thought when the OS reported 465GiB, that this number was what was "left over" of a 500GB drive in usable space.

I do not see how the above post is relevant in this thread. The post below the post you posted I thought I made it very clear that I knew the answer

Because the partition and the filesystem do not consume enough noticeable space for someone to say "I wish they gave you the total usable size".

Be careful of the Asus Rampage boards. I have 2 Asus rampage iv boards in 2 systems and I have had 5 failures. In one case the board was returned un-repaired. Other times I received replacement boards only to have them fail in short time. The general comment seems to be that when they fail it can be a very painful exercise however when they run, they run well.

Lionel did you end up sticking with the Rampage V extreme board? I have had my machine for just under 3 months it will be 3 months on 23 February. But in that time it has been in the shop 5 or 6 times we are waiting on a replacement motherboard same brand. If the board does the same thing this time which is not posting displaying a red light the error codes have been RAM related I believe. I will be asking for a complete refund it going for the same type of machine but getting else to build it who has had experience with these types of machines
