I would say, think about adding more ram first......
for $500, get a Matrox or ATi, don't think about Nvida |

GF 440 with 64MB <$500 ! |

但GeForce既色準同sharpness不及ATi或Matrox... |

你朋友用 All in one 的底板,那麼是否用Mirco-ATX 機箱? 小心張咭太大...
$445 ~ATI Radeon 7500 64MB DDR RAM
同時要考慮256MB RAM 是否真正足夠... |

agree with rtao, dont buy nVidia. |

兩樣都要up... 256mb 用photoshop 都唔會爽得去邊 |

補充少少: 市場上已有 Radeon 9200 64MB DDR RAM, 都是$4xx 尾... 不過我未試過,吾知性能同熱量是怎樣?? |

$445 ~ATI Radeon 7500 64MB DDR RAM Radeon 9200 64MB DDR RAM 這兩個不錯,都是ATI的產品吧? Matrox又是甚麼來的,另一間生產Display Card的公司?請熟識的朋友詳細解釋. |

Matrox就是出Gxxx同Parhelia那家了, 色準, 2D畫面非常sharp, 她的dual head比GeForce好好多... |

The speed of filter in Photoshop is NOTHING about the display card ability!! Some filter, like radial blur is said to be super slow and need huge among of CPU/FPU task, the faster your CPU is, the faster your filter is. If I were your friends, I would use the $500 to buy a new 1.8G Althon. Also, you may need to upgrade your RAM to 512 or more. If you use Win2K or WinXP, the windows already eaten a large among of system memory while start. If you have several hundred of fonts and plenty of memory resident programs, the total useable system memory may drop to less than 50MB! By the way, have you changed the default setting of Photoshop in the memory menu??
.ps nVidia is not that worse any others in color accuracy. But the D/A output is not that sharp when compare to ATI and Matrox. If you search for a low price and good display card, ATI 9000(pro) is a good choice. It has dual 10bit D/A and medium 3D speed.

re:raymondchan 你個friend有冇係photoshop個Preferences之類把Ram盡量分配比photoshop用,否則它只分配一部份Ram比photoshop用!? 我記得PC好似係Photoshop Preferences set,我用開Mac機係其他地方set。 |

Raymond: If my memory serves me right, you have asked opinions about this before. My own and other buddies' advice is to plug in as much memeory as possible. Given the fact that the RAM is so dirty cheap, you should have done this first. 256 is the minimum memory required and 1Gb is better. CPU speed is also a main factor |

多謝各位的意見. 我懂得怎樣set Photoshop的Ram的分配,我會幫我的朋友set的. 關於超人的意見,我覺得有道理,不過我還想進一步了解Display Card在整部電腦擔當甚麼角色,而Display Card的Ram又有甚麼用? 如果買Ram,就當然會買512M SDRAM. 部電腦用Sony的Trinitron CRT,都算幾好的啦.我估計不用onboard的Display,而加一張AGP的色會好好多. 還有一件事,我覺得我張用了好幾年的TNT2 16M都係時候換一換了. |

而家既vga卡主要有兩個作用, 一係2D加速, 一係3D加速. 由於PHOTOSHOP是2D軟件, 比張NVIDIA 5900你都冇用, 而且新既NVIDIA 5800/5900仲會係2D時減慢CLOCK RATE! 2D加速有已經是S3-968年代的問題, 當時一般顯示卡都只係MEMORY PAGE UPDATE, 粒 GPU有幾快就UPDATE得幾快, 亦受RAMDAC頂速影響最高解像度. 舊既VGA最大問題就係 畫面視窗移動慢, 你可以係PHOTOSHOP內開一張大圖, 再以100%VIEW, 用手仔工具捉 著圖的中心, 隨意移動老鼠, 張相就會跟著手仔移動, 快的顯示卡的影像全無時滯, 差的是然又崩又爛. 以現是幾百元一張的AGP顯示卡, 任你點郁都唔會又崩又爛, 但 當你個MON設定至1280X1024X32BPP顯示或更密, 快卡慢卡立見高下. 唔同卡的DAC係有少少分別, 但分別主要係有幾SHARP, 而唔係色有幾準. 夾MON同卡 就好似夾鏡同菲林, 唔係貴O野就一定O岩口味既, 好似我部既一張S3-SAVAGE2000 比部慢機用, 估唔到D藍色特別艷! 對比度比其他色都大了, 同睇慣的NVIDIA及ATI 簡直就好似用左RVP咁, 死未!

很吸引的話題! 我也正想換張好顯示卡做圖片用,但從來不會打機的!價格合理的話,有什麼推薦?最好注明在哪裡買得到。 |

for 2D performacne both ATi and Matrox are good... |

For photoshop you need large (and fast) hard disk and many ram if your image is very large or you open many images at the same time with many layers. Harddisk is used as virtual ram and temporary storage. If you need to have faster filter, you need very fast CPU or dual CPU (dual cpu has better performance, as photoshop has capabililty to use dual cpu when rendering). Display card speeds up the redraw speed in 2D performance in photoshop, so you don't have to wait so long between redraw of images e.g. when enlarge, redraw after applying filter. |

明天深水步有電腦展,就去看看,準備出手了. Sorry,愛上攝影後甚少看電腦資訊,所以不太清楚電腦市場. 看情況,升級RAM最好,但現今RAM的主流是哪種,SDRAM還有那些底版可以用?(買了512M RAM後,擔心日後換電腦不可以用,幫別人升級還有想得那麼多,那麼遠,人情真難做呀.) 希望那該死的Onboard Display不要拖累整個System,令那768M RAM無用武之地,也會令我丟臉. 想不到在這個話題學到不小與攝影有關的電腦知識,手札以前好像比較小討論.
