Curious about the 7850

Why do you want to use a TV? TV's don't have the picture quality of a monitor.

I know, btw im getting 7870 i heard its worth the difference. im using tv cause I'll save the money for a nice monitor

first off, size of the tv does not impact the GPU's performance. it's the resolution that matters. assuming that it's native resolution is 1080p, all other possible problems aside, then yes, it would be good for gaming.

if it's native res is 720p/768p, then the 7850 would actually be an overkill if you have no plans to upgrade to a 1080p tv/monitor.

i highly recommend you to test out your tv for problems before using it as a PC monitor. just connect a desktop or laptop to the TV via HDMI, and see how the picture quality is and test if there are any other problems like input lag, ghosting, jagged texts, washed-out colors, etc.

ok thanks

I have the 7850, and i've successfully overclocked it to a 570 levels. Which maxes out all my games 1080p.
But if you want the 7870, go for it! It has more stream processors.

Truly, the size of the tv doesn't matters what matters is the resolution if your tv has a maximum resolution of 1280x720 or 1366x768 you will be able to play games at the ultimate settings on the HD7850 and if it has a resolution of 1920x1080p then i guess you'll be able to play games at highest details with moderate settings and respectable frame rates.
Its a nice card. If you can spare $40 more i would recommend you to buy a HD 7870 coz i'll allow you to play at full details if your monitor is 1080p else 7850 is a great choice.
Cheers.
