Is it true that 4800 serie doesnt support monitor bigger than 30 inches?
Both the GTX 260 and the HD 4870, and in fact most modern video cards, support 2560x1600. That's a 30" monitor. There are TV's with 1080p which can be a lot larger than 30", but their number of pixels is smaller than a 30" monitor's. That is, it's 1920x1080. Those are supported all right by both cards too.
AFAIK 2560x1600 is the biggest resolution available in consumer products. OK, technically, both HD 4870 and GTX 260 can be connected to two such monitors in DualView mode so you can say you have 5120x1600.
