Nvidia GTX 660 Ti With HB Z600

I'm a video editor and graphics designer ,

My desktop PC Spc. is :

Core 2 Quad Q9650 3.00 GHz with 12 MB Cache

12 GB Ram

Nvidia GTX 660 Ti

GigaByte Motherboard GA-EP45T-UD3LR

Now, I want to use HP Z600 Workstation But With My Nvidia Card

2 Processors Intel® Xeon® Quad-Core Processor E5620 2.40 GHz, 12 MB cache (24 MB Total) , 1066 MHz memory

20 GB RAM

Nvidia GTX 660 Ti

Motherboard Intel® 5520

So,

1 - Can I use my graphic card Nvidia GTX 660 Ti With This Workstation HP Z600 ?

2 - My Programs Performance & Video Programs Rendering Will Be Faster Or No ?

Thanks
