請助: 幫忙看一下規格

請教各位大大:
公司欲組一台desktop供pro-e繪圖用, 零件有時需建立不少曲面,

以下是報價的規格:

1. HP Workstation XW4400x Dual Core
- Intel Core 2 Duo E6300 1.86 2MB/1066
- 1GB(2x512MB) DDR2-667 ECC
- 160GB SATA 3Gb/s NCQ7200(1st)
- NVIDIA Quadro NVS440 256MB PCIe

2. HP Workstation XW4400x Dual Core
- Intel Core 2 Duo E6300 1.86 2MB/1066
- 1GB(2x512MB) DDR2-667 ECC
- 160GB SATA 3Gb/s NCQ7200(1st)
- NVIDIA Quadro FX560 128MB PCIe

請問顯卡哪一張會比較跑得順? ram 1gb是否已經足夠應付?

謝謝回答~!~!
