I'm late to this thread too. Proud that i have been here 13 years. Still want to build a new computer :(
2) Message boards : Number crunching : Seeking advice on components for a new computer. (Message 1223962)

I will be building / assembling a new computer in Mid May. I would like to solicit advice here on the components to choose to optimise my S@H crunching. I will leave my computer running 24/7 so power usage and cooling are issues.

I live in Brisbane, in Australia which is sub tropical in climate. My home is not air-conditioned and in mid summer temperature inside is often in the mid 30’s C. Currently I buy my electricity at $0.21 per kilowatt hour.

I am not a gamer, and am somewhat price conscious. This system will be my primary computer for hopefully the next 2 to 3 years. My main use will be web browsing, using Microsoft Office and Wolfram Research Mathematica, and of course running Seti@home 24/7.

What is the best/ fastest/most efficient single graphics card to use? Nvidia’s GTX680? If so would there be any advantage S@H WU crunching wise in buying a 4GB card over a 2GB card?

Should I use a new Ivy Bridge chipset Mother board and the i7-3770K over the older Sandy Bridge Motherboards and i7-2700K?

I would like to experiment with overclocking, but do not want to use water cooling. What air cooling do you recommend? I would like the system to be as quiet as possible. What case do you recommend? I live in a built up area so dust/pollution may be an issue.

How much RAM and what type should I use to optimise my WU crunching?

Would a SSD help in speeding up WU crunching?

What PSU should I get? Is it worth forking out the extra for a Gold rated PSU over a Silver or Bronze. I do not expect to have more than one graphics card.

I have already bought the monitor – a Dell 2711. I will be running Windows 7 and will upgrade to Windows 8 when it comes out

Lots of questions I know. I would appreciate any advice readers may wish to offer. Thank you.
3) Questions and Answers : GPU applications : Seeking help to maximize theWU utilisation of an NVIDIA GeForce GT 320M graphics card (Message 1038555)

Seeking help to maximize theWU utilisation of an NVIDIA GeForce GT 320M graphics card

Hello, embarrassingly I must admit that I am an 11 year clueless N00B. I just install Seti@home on my computers, and let them run.

A fortnight ago I bought a new laptop, an Acer Gateway NV59C V1.06. My first computer with a GPU that Seti@home can use. I am eager to maximize the Seti@home work this laptop can do.

I run BOINC Manager Version: 6.10.58 wxWidgets version: 2.8.10.

I think I have set the preferences to maximize processor usage with ticks to:
computing allowed while computer is on batteries,
while computer is in use
use GPU while computer is in use.
While process usage is less than 0

For other options I have the following:
Switch between applications every 60.00 minutes
On multiprocessor systems use at most 100% of the processors
Use at most 100% CPU time

Are these the most efficient settings for WU crunching?

When I view tasks I see 5 applications running with one for each of the four threads of the core i5 CPU and the fifth application has the following information in the status column (Running 0.18 CPUs + 1.00 NVIDIA GPUs)

I got the following message:
1/10/2010 6:16:57 PM SETI@home Message from server: NVIDIA GPU: _("Upgrade to the latest driver to use all of this project's GPU applications")

Can someone give me advice or directions on how to do this?

The specifications of my laptop are as follows:
2.40 gigahertz Intel Core i5 M 520
Windows 7 Home Premium (x64) (build 7600)
NVIDIA GeForce GT 320M [Display adapter]
