Of course, you will most probably want to hear by the browser porting developers. Interesting if you could try ask this question in the right place as well. This most probably addresses at best the specific browser developer teams who run and test on OpenBSD supported platforms. > I'm thinking about the X supported ones, with KMS ready and working. Namely intel(4) & radeon(4) at the moment. Nvidia video cards are a big disappointment (hint: don't buy), and the browser still works OK even there. The disappointment is in the nv main board chips as well (on many levels including technical matters) which is unrelated to your browser question, same maker though. Having used nv(4) as well which has no drm(4) & KMS support, I can't make a significant difference on the browser level based on video card toggle in the same system. This means the browser is squeezing mostly the main system CPU like nothing else, and if you're several years behind there, running JS is not an option (there may be other reasons for this). With video / media players, I've been quite happy with radeon(4) full screen play at vast resolutions up to 2560x1440, and again the limitation has been the CPU. > Is there any visual noticeable difference if one is using a low end > ATI card versus a more advanced one? Take for example ATI x1300 vs. HD > 4370 or so. Not in my experience. How about considering a low end something more modern (which you can still pick new in the shops) with low power usage and thermal output, like 5450/6450? These work OK and are affordable, if your main board does not reject them, so if you're just looking for a solution, this one is tested and works here. > Some threads already discussed about CPU hits on browser performance, > but nothing about GPU. For me, the big hit on browser performance is on the CPU, from a user perspective. If you strongly disagree, please complain at the proper place (not me).
