  1. 600W is enough for any single-GPU system. I'd sell the 7850 and get a 7950 or 7970. Or you could get a second 7850, though that would be pushing the PSU and the motherboard IIRC can only do 3.0x16/2.0x4 CF, which would be a bit of a bandwidth bottleneck. Might work though.
  2. That system should be fine for 1080p gaming. Remember that the physical size of the display doesn't matter, just the resolution.

    Only worthwhile upgrade would be a stronger GPU, and 7970 Ghz is about the best you can get. Go for the Sapphire Vapor-X 3GB if you can find it in stock, though the Gigabyte and MSI cards are all good.

    That 600W supply will hold the system just fine.
  3. A 7850 would be fine at 1080p. TVs are not meant for PC gaming and can have input lag and generally do not look as good. Emersons not real high up there either. Might want to borrow a friends monitor and make sure it's not the TV first.
  4. ya
    ive herd about the input lag and was also cerious about the quality and colour from the monitor

    but ive been playing an Acer 1440by 900 rez 21inch for the longest time
    i wanted the TV just for watchin netflix and bluerays or DVDs when i get a blue ray player

    but when i pluged it in i tryed out some games and there very good no input lagg no bad colour great looking
    to the point i hate going back to the 1440 by 900 acer monitor
    i only wanna play on my new 39inch emerson 1920by 1080p HDMI
