then buy radeon 5670 or 5750. support of opengl 3.2 has every card from radeon 2xxx series.
thx for your answer
what about HD4 models ? (4670 ?)
do you think 512MB is enough or do I have to prefer 1GB ?
sapphire models seems to be noisy at full load
is there anyone who can suggest me a (almost) noiseless single slot model ?
HD 4xxx as i say support OGL 3.2 too. but i will buy 5xxx series card becuase it can happend that OGL 3.3 can require shader model 5.0 capabilities so it will run only on DX11 card.
i think some card from 5xxx series is better option.
i have two card from sapphire. 3850 and 5850 and both is inaudible in idle and under load i heard only little airflow.
when you buy card with reference cooler it is same for every brand.
I ordered the HD5670 model from XFX, cheaper than sapphire models I can found in France
thanx again for your help
