I am ordering a Dual Monitor new PC. I would like to record TV programs on my hard drive & watch TV on one screen & work on PC on a second screen at the same time. Can somebody please explain what extra hardware & software do I need to order in new PC ? Also I have a choice of two video cards namely : 128MB PCIe(TM)x16 NVIDIA(R) GeForce(R) 8300GS w/TV-Out, VGA & DVI 256MB PCIe(TM)x16 NVIDIA(R) GeForce(R) 8600GT w/TV-Out & Dual DVI The 256 MB is more than twice in price. I am not a gamer but I do analyze stocks charts with live streaming data with graphic software. So do I need 256 MB or 128 MB would do ? Thank You.
