Need help on upgrade Graphic Card

I'm using a computer list below and i want to change the Graphic card because I'm gonna buy a HDTV and connect it with the Graphic card.

CPU: Intel Core 2 Duo E6420 2.13Ghz
Main: Gigabyte forgot the model :(
Ram: 2GB x 2 Corsair Buss 800 and 1Gb x 1 Kingmaxs Buss 800 ( Total 5GB - System running in Flex-mode )
HDD: Seagate 80Gb 7200rpm, Seagate 1Tb 7200rpm x 2
VGA: XFX 9600GSO 768mb
PSU: 560W Acbel
Monitor: LG 20", Dell 21"5 ( Running in Dual Monitor )

i want to watch HD movies on the TV and play game in med or med+ settings :D

I'm considering change to HIS HD 6790 and HD 6770 for more out put: 2DVI and 1HDMI, so which one will be the best for my requires ?
And can my PSU handle it ?, will my CPU or Mainboard bottleneck it ?

Thanks and excuse for my language, I'm not good at English :(

  1. It is a matter of what you are willing to spend.
    $100 gets you a 6770.
    $120 gets you a 6790 which is a small performance increase.
    Setting your budget higher, $150 gets you a 6850 which gives a sizable performance increase.

    Also, for the moment, you can connect your current card to an HDTV, you just might have to get a DVI-HDMI adapter.
  2. So, my computer won't bottleneck and enough power for those card ? even HD 6850 ? if yes, i will get the 6850 :-? and yes my current card can connect to an HDTV with a DVI-HDMI adapter but the problem is i had 2 Monitors and 1 HDTV and my current card had only 2 DVI connector :( i need one more HDMI connector for the HDTV and this is the reason i 'm gonna upgrade it, and Thank you :D
  3. Whether your system bottlenecks on your CPU is dependent on what you're running. Some games are more CPU hungry and some are more GPU hungry. Your Core2Duo is still a decent CPU and will continue to work at least as well as it has so far no matter how fast your GPU is.

    DVI and HDMI are electrically compatible. A simple plug adapter will let you use one with the other. Getting PC audio to work over HDMI can be tricky, though. AMD has supported audio over DVI/HDMI better than nVidia, in my experience. Even having HDMI on the gfx card is no guarantee that audio will automatically work. I had to rig up a jumper to the external SPDIF connector on my motherboard to get audio out on my 9800GT's HDMI port. YMMV

    that cpu will bottleneck hd 6850 in most cpu dependent games.
  5. get the sapphire hd 6770 in cheaper price that will give u a performance boost and higher then that may cause bottleneck.

    or this for more performance.

  6. Faster graphics cards don't cause bottlenecks. Your CPU may not be able to keep up and you won't be getting the full benefit of the faster GPU but no GPU, no matter how fast will ever cause your CPU to slow down.

    Just remember though: Your next build probably will have more than enough CPU to keep up with that card so don't overlook investing in the future.
  7. and about the PSU do you think it had enough power ? I forgot i also had a DVD-RW
  8. Best answer
    yes your psu is fine to run hd 6770 and whole system.:)
  9. Thank you all i think i had the answer :X
  10. ok good luck and ur welcome.:)
