2 Camera iMac HD Config?

Would the following iMac Configuration
handle 2 camera- live HD streaming
with BoinxTV?
thank you

2.8GHz Quad-Core Intel Core i7
8GB 1333MHz DDR3 SDRAM - 2x4GB
1TB Serial ATA Drive
AMD Radeon HD 6770M graphics processor with 512MB of GDDR5 memory

The same as in your other thread applies here. What kind of Mac would that be? How do you plan to capture the camera inputs?
