Video editing PC - Assistance required

Afternoon all,

My dad has recently expressed an interest in buying a new PC. In the near future he will be required to do some relatively amateur video editing - most likely at 720p as opposed to 1080p.

He is a fan of dell, and has seen the Inspiron 620MT. The specifications are as follows;

Intel® Core™ i5-2310 Processor (2.90GHz, 6MB)
6GB1 Dual Channel DDR3 SDRAM at 1333MHz
1500GB2 SATA hard drive (7200RPM)
NVIDIA® GeForce GT 530 1GB DDR3 Graphics Card
Blu-Ray ROM Drive (read/write CD/DVD & read Blu-Ray Disc)

The cost of the above is £600.

I believe he can get a much better rig for his money. I wonder if someone could suggest some alternatives. The GPU is fairly poor for a start.

Primarily it will be used as a general use PC, for watching youtube videos/general internet use/watching DVD's etc. However, as mentioned it will have to be able to fairly seamlessly edit 720p video. He does not game at all, although if he were to get into it it certainly wouldn't be BF3 or the like. He would want a Blu-Ray R/W.

I'm hesitant to build one for him, but in the right circumstances may be convinced.

He wouldn't be overclocking anything, would want something reasonably quiet and very reliable.

I wonder if anyone could put some ideas forwards? A couple of rigs would be lovely. Perhaps one that costs the same as the 620MT (£600), and one which just costs whatever you deem suitable for his needs? There's no point in him spending £600 on a PC if he won't use £200 worth of it, if you know what I mean.

Many thanks,

Rabbithutch.

Edit: He already has a monitor, peripherals and an OS. Only the tower is needed.
 
For video editing, you can never have enough cpu power or enough RAM. HDD speed is also massively important. Generally the GFX card makes no difference so onboard is fine, and will handle all the other uses perfectly (except BF3) That said some adobe packages can make use of a good gpu but for that to be taken into consideration we are talking top of the range £400+ cards so will count that out.

720p editing can be a serious hog on your resources.

Any case + reasonable psu will be fine.. so you can choose.

The SSD is for OS/Scratch disk.
(do not get a sandforce controller one - they are insanely slow when dealing with video)
2TB for storage.
16gb ram yummy (this will be used whilst editing) - note a 64bit OS + 64bit editing application will be required to make use of it.
Motherboard has dvi out and makes use of the onboard gpu.

Without going for a tasty dual xeon workstation setup you will struggle to get better performance within a reasonable budget. (no doubt somone will proove me wrong ;) )

Yes over budget... The CPU is expensive, that could be toned down, the 2600 does hyperthreading which video apps should make use of, so there is a reason for it.

Also another possibility would be a AMD Phenom II X6 - they provide great performance when encoding video. I have no idea what motherboard etc would be suitable though. A good avenue to explore though.
 
They are marginally slower with incompressible data irrc, however that's not the issue.
They perform pretty well, not the best with small incompressible bits of data.

They have very strict ware leveling controls in the firmware, which puts the drive into a "crippled" mode, this is to "protect" the drive against waring out.... what it actually does is gimp the drive to silly slow speeds to prolong it's lifespan.

Benchmarks don't pick up on this, as only a few gb's are written.

Most users who do standard things such as games, windows apps, and light benchmarks don't encounter this scenario.

However video editing results in vast amounts of data quickly written to the SSD which triggers this "safety" measure.

This is not to be confused with TRIM in any manner. I'm pretty sure once this happens, that's it the drive is locked permanently, a secure erase etc will not undo this "mode".

You do need to write a fair bit of data quickly to the drive for this to happen, however when video editing you certainly don't need to try.
 
you could always get one of those SLC drives for ascratch disk, along with a bigger MLC drive for OS + programs

also, depending on what program you use an Nvidia graphics cad could make a massive difference in the editing speed. i know there are some programs that can use the cuda cores of the nvidia card for video encoding, but im not so sure about editing

*edit*
looking around it seems there is some stuff that is made vastly faster by Nvidia's cuda cores

SLC drives rock but don't they cost the earth ?

Indeed Some apps do support CUDA which is great for both the editing (mostly effects) and the encoding side too.
The 2600 setup listed provides the option to use the onboard GPU for assisted encoding using quicksync, which is comparable to cuda assisted encoding.

That said I'd personally avoid these gpu assisted systems, they make things faster at the cost of quality. The theory is great, but in reality in imo they are just a gimmick, as you are so restricted to what codec is used, the reduced quality etc.

Throwing the same money at other areas of the system will provide greater performance, and if on a budget - significantly less power consumption over a year than a dedicated gpu.

That said, cuda is a lot more versatile than quick sync. It could be useful at the editing as well as the encoding stage. I think they are just a bit situational.
