How is it?
Need to replace some desktop computers at work, but i3 too expensive so might go G640. Is it worth the money?

Just need to run Office 2010, open large excel charts, and browsing internet.

只係做上面d要求,應該夠曬用,唔洗用i3

More than enough la.
But also consider upgrading the RAM as the internet is becoming increasingly demanding.

4gb enough?

current quoted configuration is
G640 / 2gb ddr3 ram / win 7 pro 64 bits

Should be enough with 4GB
BTW, why would they quote a win7 x64 with 2GB ram?

dunno, this is one of the standard lenovo configs

For your purpose, G640 is enough, but 4GB RAM is recommended

作者: tat0801 時間: 2012-9-4 17:12

G640 with 4GB ram = OK

Yes
我 manager 有個好大既客, 一年百幾二百個 project
呢個 chart 就係今年到目前為止所有既 SKU
有埋詳細報價 + 圖
佢自己開就 ok
但麻煩既係要經 network 開, 因為 shipping / accounting 都要睇
佢又唔肯擺上 internal network

i think yr company needs a ERP / CRM system rather than just using Excel to manage customers, quotation or other related stuffs

not really worth it
only 4 sales teams anyway
everyone calculates prices differently and apply different margins depending on customer, would be too much trouble just to develop software
i am fine with using excel, i keep a separate sheet for each project/customer

我係剛剛check cpu野先注意到。 benchmark 差無幾

但計excel時, 真係i7好過i5, i5好過i3... 大約係咁。

若你只為精打細算, 當然係降CPU grade, 將省到的錢轉去投資在記憶體和SSD了。但廠機冇咁大彈性, 所以中下價時迫住用錢買i3/i5做performance方面提升。

若然你想要performance, 廠機換G乜乜再加ram, 省幾百未必咁jetso。花多幾百i3或一千i5又未必最好。睇預算決定吧, 冇比較下G乜乜唔會覺特別慢的~~ (大既office file就有分別...)

其實 formula 唔多, 純粹係因為多圖所以個檔好大...

Take these points with grains of salts cause I am not the most intelligent hardware guy  here.

I think  big MS office files request lots of RAM and CPU. While there is a budget constraint, RAM is currently a cheaper upgrade. Unfortunately, formula or office functions or pictures are both CPU and RAM hungry.

These features reads and write from HD to RAM frequently. Now Office softwares will break the R/W sessions small, but that will mean frequent I/O HD to RAM to CPU to RAM to virtual memory i.e. HD and then a multi-tasking sessions initiate another cycle of I/O before the last cycle completes and release all the resources. In the old days, read / write took place in big chunk, so throughput was important and can somehow be the bottleneck. Now softwares are so "intelligently" designed but many simultaneous I/O took place. Memory controllers are in CPU, I/O controllers are at the chip sets, RAM chips and HD are hardware-dependant as well.

I.e. The way things are designed is to ask you for money to upgrade ALL parts if performance is to be optimal.

I believe in your case, RAM and SSD may address the most hidden bottlenecks if you are quite sure there are no calculation-intensive activities going on with your office files and internet applications.  But then the PC industry is prohibiting customers from choosing these upgrade options unless you opt for the ultra-portable (i.e. expensive) solutions or top-of-the-line built-to-order PCs.

At the end, I am not able to help you any better than what the PC vendor has originally offered you. You paid less (to PC vendors), you got more bottlenecks.
