For those who have 256MB x1950pros, do you get any pause or lag issues when folding with the GPU client? Apparently there are reports that 256MB is the cause for most of the issues, but some people report that the even the x1950pro 256mb doesn't have any problem. Main reason is I'm going to pick up the AGP x1950pro and was planning on getting a 256MB version until I heard about them having issues.
