Adobe creative cloud programs system requirements

Hi,

I have a question, My mac is from 2011. I have High Sierra 10.13

• a Processor: 2.4 GHZ Intel Core i7
• Memory: 16 GB 1600 MHZ DDR3
• Graphics:  AMD Radeon HD 6770M 1024 MB

                            Intel HD Graphics 3000 512 MB

• And I have a 451.88 GB hard disk space. 

I am not sure my mac cas a video card. Do I need a Video card?

I was reading and they said I might need this? 1 GB Video RAM (VRAM). 2 GB of dedicated VRAMI 

How do I know if my Intel processor has at least 64 bit support?

I would like to know if my mac has enough space and the right requirements for me to download the adobe creative cloud. Creative cloud file will take 233 MB. After that every app take its own space to be downloaded. How much space does each app takes on my mac? How much RAM do I need to run the creative cloud programs? I will be using photoshop, illustrator and Lightroom at the same time. I usually have those 3 programs open. 

THank you,

Kindly,

S.
