your in the same shopping situation as me. I have many ideas and choices, but, regarding these two.
1) that 7600 card will support them but not very well, If your playing games, your frame rate will be very low at that resolution even in SLI.
2) The samsung does not support all Hidef feq's so, watching blue ray or other such material is out of the question. The Samsung does seem to have the best favor with gamers though.
