dubbing with mtc video slave

hi

i do all dubbing with MTC video salve. so i setup a second pc just for MTC software. system details is:

core i7 2.8, geforce 8500 gt (guess its 256mb video ram), win 7 ult, 8gb DDR3, 600w power supply.

i want to play big mp4 video file or better but i don't know much about video stuffs. actually how much video ram should i check before buy a good video card?

is that 2gb card or 4gb? which card?



and i want 2 display.. one is in the control room which will be 29inch and another in the dubbing room that i'll place a 19inch. is it ok the use different size display by using 1 pc?



thanks a lot :)



** i was trying to play a 16mb mp4 file and geforce is not playing smoothly!!
