Yep 8044 and 8043 are slightly lower in the PPD, but I find the 8044 works a lot nicer with sharing resources on my computer with other programs... a lot less of the freezing/micro stuttering with watching youtube, etc while folding.
Don't forget this version of the
[email protected] is beta... so they probably have you there ;)
Edit 8045 WU and it's still happy to fold, although the PPD is still worse than a 8018.
