Workstation for Development/Testing

Where are you? Somewhere in Europe? You have an Akasa cooler selected, and those aren't available in the US as far as I know.

For what you have specified you can certainly do better.

Gigabyte 770 DDR3 AM3 MB

Ah well you don't exactly have the same prices over there anyway.

A P45 DDR3 board is probably what you want then. Probably not that one though.

I think this would be great and has a good price:
GIGABYTE GA-EP45T-UD3LR

This UD3R would cost a bit more but is probably a bit higher quality:

Look for low voltage on the DDR3. Corsair makes more than one model of DDR3 1333, but both are CAS 9.

If you are fine with the slower RAM, get some that operates at 1.5V at least. Kingston and Mushkin both make affordable 4GB kits with those specs.

Or, get faster CAS 7 RAM for around the same price at 1.7V or so.

A quick look at a few EU sites didn't get me much. I found this OCZ CAS 7, but it's pretty heavily volted:

The Akasa does look like a good affordable cooler. Similar to Arctic Cooling.

From what I can see, the video card I linked will pull a lot less power than the 9500GT, although they are priced about the same here and both will work.

The Sonata is a pretty good choice for a quiet case, and the EA500 PSU that comes with it is high quality. A Corsair 450VX might be a bit quieter, but then you would still need a case.

450VX:

The Velociraptor is of course faster, but are you sure you want to spend that much? A 640GB Caviar Black would cost less and be almost as fast. Or, if it's really that vital, a newer SSD drive perhaps for your data:

Then some smaller WD drive for your OS and whatever.

That's about all I have for you. There was nothing terribly wrong with any of the parts you listed, these are all small improvements.

Depends on how far in the future you want to be able to upgrade memory and if you want to go up to larger capacity memory sticks when you do. If you just anticipate getting more of the same capacity memory, I'd just go with the cheaper of the two. For longer term, DDR3.

Also, if your devs are running a lot of processes, especially heavy ones like active local databases, working with virtual machines a lot, or use compilers that can take advantage of all the cores, I'd think about getting a quad core. Keep your devs productive, when they are coding, by not making them wait for the computer, if possible. Testers usually won't need a quad core.

+1

I do think the DDR3 versions of the P45 boards play better with 16GB than the DDR2 versions also. You would have to do a lot of research and work to get, for instance, my P5Q-E running 16GB of DDR2.
