Hi buddy i changed my graphic card now i have his 6850 when i run the games like black ops at ultra setting i think it worse than gtx 275 gigabyte super i mean alittle fps !!!!!!!!
More about6850 gigabyte super 1792
they are pretty similar in performance. but i would take a 6850 over a gtx275 anyday. the 6850 should be slightly faster overall but may be slower in very few cases. What resolution are you playing at? what cpu do you have?
