its looking septemberish for socket F, a month later for release of the desktop normal chips, am2 socket, and 2-4 weeks after that for availability.
almost certainly a decent amount faster per clock than penryn. i still don't know if amd will have sse4 in it. assuming they don't, then anything that uses sse4 might be significantly faster on the penryn for a while till a revision brings us sse4. but in all likelyhood it will just be a few encoding programs, and maybe only certain situations will it show its extra juice there. other than that no real improvements are in penryn.
but remember, honestly, if gamings the most intensive thing you do, then you'd be hard pushed to see the difference between a 2.2Ghz X2 and a 3.3Ghz quad core penryn, likewise a new phenom overclocked to 3Ghz would give about the same speed in games as a 2.4Ghz conroe.
you get a monitor you can afford, you match the gfx to play at the res of the monitor, then you stick any cpu over 2Ghz with 2 cores on it and you're fine.
