My Specs from the 'puter I built a few years ago now... before photography was a priority. I am due for an update but that means Mother Board RAM SSD and CPU which costs money lol
Plus I am waiting for DDR4 RAM to get into the system, no point buying DDR3 motherboard and CPU at this point as it leaves no upgrade path really.
Processor: Intel Q9450 2.66Ghz Quad Core, If I am doing something demanding I'll overclock to 2.9-3.2GHz
Ram: 4Gb DDR2 800Mhz
Motherboard: Asus P5Q Premium
HDD: Gskill 64GB SSD, Segate 1.5TB in the Box plus about 5TB of drives I swap through a dock.
Case: Antec 900
Graphics: ATI Radeon 5870 1Gb
PSU: 800W Thermaltake
OS: Windows 7 ultimate N
As for the sluggishness, when your run programs that are intense such as PS and LR there are a number of choke points. In no particular order and divided into upgrade options or maintenance/Tweaking options:
Upgrades:
- your HDD is probably one. I would look at getting an SSD to run your PS and LR from separate to the operating system, they have next to zero latency and significantly faster read/write speeds. if you wish to stick with this you can improve it's performance... See Maintenance.
- RAM is another. I only have 4GB and will occasionally max it out when doing some stacking with LR and PS open + I use Firefox which is a little more demanding than chrome on the Ram side of things. 16GB should last a while, and is one of the best bang for buck performance upgrades.
- Graphics. This is important if you are running a monitor with large colour gamut as some cards don't produce enough bit depth in the colours for decent monitors. the GB's are not a huge thing at this point nearly all cards come with at least 1gb which is plenty.
- CPU should be ok if you do your maintenance.... see maintenance.
- PSU.... or Power supply unit, if your have gone along and made updates, GPU especially, you might find it sucks more juice than your current one can supply and make for some stability issues.
Maintenance/tweaking:
- if you have a disk drive (not solid state) then regular defrag is essential to performance. Defragging SSD will shorten their life.
- remove the junk programs, it will reduce the number of processes running in the background.... I like CCleaner (aka Crap cleaner). It allows you to do most important stuff from the one place. Also let you scan the registry and clean up all the traces left by programs when you uninstall them (it's free).
- you can go down the line of Overclocking. CPU RAM, motherboard GPU but you will need to know what your doing otherwise you can fry stuff. I think this is unnecessary for you.
- Clean inside the box to keep things in there cool and prolong their life . A can of compressed inert gas (not air) will do. compressed air has moisture. Moisture + computer innerds = BAD.
- Back up everything to external drive
- Back up everything to external drive
- Back up everything to external drive or cloud... just encase you forget!
There is probably a whole bunch of things I missed by this is just a start.. and it's 1:45am
so I am probably a zombie by this stage... no quite sure though.
