    i7-970 vs i7-950

    nantoskey

      I am slowly but sure getting close to my budget build selections..  I will mostly edit HD JVC HM700 & DSLR footage.

       

      Is it worth it for me to spend the extra bucks from i7-950 to i7-970?

          NAN,

           

          Without knowing more, I'd lean towards saying the i7-970 is worth the extra outlay.

           

          To be more more certain of which would be best for your needs, please tell us:

          - what is your total system budget?

          - what components have you selected so far?

          - what are the specifics of your hard drive plans, including hardware controller details if you will use one?

          - will you be overclocking your CPU or sticking with stock settings?

            It depends on your workflow and your delivery format. If you usually deliver to MPEG2-DVD or web, I think the price difference is pretty steep, but if you usually deliver to H.264-BR format, there is a definite performance advantage from the hexa core and the larger L3 cache. If your workflow is edit and export, without the need to render for preview purposes, it makes less sense to invest in the 970, but if you have lots of multitrack and multicam work, often use previews to check your work, use DL to AE, then it may be worth to invest in the 970. I have no idea how tight your budget is with all the other components, but a fairly common approach is to get the fastest CPU one can afford and forget about the other components, especially disk setup, which ultimately can end up as the weakest link. Disk setup is often overlooked and to give you an example, just today I configured a server, using spare parts I had laying around and with a 7 disk setup (1 boot and 6 x 1 TB disk for storage) the cost is only € 650, but adding a good raid controller, BBU and cache, increased the cost to € 1,715. (All excluding VAT). The message actually is: Often it pays more to get a decent disk setup and forfeit a top-notch CPU to get a more balanced system. Raid controllers and disks do add up to the overall cost.

              Thanks.

               

              Ideally, my budget is 3K ... with monitors, but I could go up to $3500.

               

              I want to deliver to H.264-BR format and hope to incorporate more DL AE.  Sounds like it may be worth it ...

                Nan,

                 

                Given the list you gave and the budget you indicated, I would suggest adding another RE4 drive to that raid5. It will make your disk setup significantly faster and give you more storage space. But that will also restrict you from further expansion. 3Ware is not the fastest controller and 4-ports can be limiting. OTOH, going for an 8 port or more controller, will bring you out of budget range.

                 

                For the rest, your list looks very good. I would opt for the 970 in relation to your delivery format.

                  NAN,

                   

                  Like Harm just said, the disk setup is often overlooked, and yours having a 3 drive RAID does seem underpowered compared with the rest of your system.

                   

                  For your budget I'd suggest the i7-950 (or SB 2600k actually, another 32nm solution like the i7-970), and build up your RAID array to at least 5 drives.

                   

                  If your price point is really firm, many users here are going with multiple 2x1TB Raid 0 arrays off their motherboard and then handling redundancy with an external backup solution (set up following Harm's drive configuration tips).

                   

                  Regards,

                    My opinion is go for the best CPU first and consider the lowest priority item on the list the 3Ware mediocre RAID controller as a last resort.  Do consider the dual motherboard RAID 0 as a starting point as suggested but be sure to at least have another large disk drive for archiving

                      I can't get invest in high buck RAID controller now ... but would really like some redundancy.

                       

                      For about $150 more I could get the Intel RS2BL080SNGL as I've seen noted on other posts as an OK budget card.  It has 8 ports.  But transfer rate is 600 MBps Per Port as opposed to 3ware Up to 6Gb/s ... am I missing something?

                       

                      I know people have not raved about this card ... but a fellow forum mate has had good luck with it.  Though I need to confirm if he's doing RAID5.

                      I think 4 port/ 4Tb for storage would work for me for awhile.

                        OK then, how about taking the 3ware RAID up to 4 drives and addiding another 2 7200 rpm drives in RAID 0 that CS5 could use for cache, scratch, etc. but would not be used for media, projects, etc. where you would need the redundancy?

                            Looking at the specs that you provided are hard to explaining 600 MB/s (there are no disk drives that are rated at 600 MB/s or 4.8 Gb/s) except that maybe a non-technical person wrote the Intel spec.  If you look at this Intel literature you will see that the SAS Interface transfer rate is 6 Gb/s, but unless there have been changes not appearing in the Intel literature the SATA transfer rate is listed as 3 Gb/s.  Incidently this product is manufacturer by LSI as the MegaRAID SAS 9260-8i which does not specify a seperate SAS and SATA transfer rate it just specifies a Port transfer rate of 6 Gb/s.  Confused?  So am I.  Maybe Eric at ADK can explain.
