I'm looking to build a new PC used to process photographs, converting Canon 20mb+ in size RAW files into JPEG. At current i can be converting 100's/1000's of pictures at a time so speed is quite important and my current system isn't up to the job. I'll list the spec i'm thinking of and would appreciate any views on what i should upgrade or do differently.
Processor - i7 2600, 3.4ghz, may try and overclock this to around 4.5ghz.
Motherboard - Gigabyte GA-Z68X-UD3H-B3
Memory - 8GB, 2x4GB 1600Mhz
Graphics Card - ATI 6870 1GB
Hard-Drive - Western Digital 1TB 7200rpm
Power Supply - 500W Antec
Operating System - Was planning on using Windows 7.
Any help with alterations/views would be greatly
