The 8xx PD's don't have HT support. HT support will not come until Pressler or Conroe...forgot which.
It really depends on what you're going to do the most. If gaming is more of a concern then the 6xx would be the better choice.
If multi-threaded apps will be used more the 8xx CPu's will be the better choice.
That is right now though...right this very minute. When Pressler and Conroe comes out it will change the game again. Those CPU's are so powerful for both types of apps it will not matter.
Saying all that, if you went with a 6xx or a 8xx either one you will not be disapointed even if you went with the 8xx for gaming and the 6xx for multi-threaded it's really not gonna matter all that much. Both are strong performers. On Video Encoding, I would definitely go with the 8xx though as it gives a fairly substantial gains in that department.
The 6xx will be the better OC'er and the better gamer and bencher, but the 8xx will do the heavy multi-media a little better.
When the 975x boards come out, and the Presslers hit the market, some heads are gonna roll again! LOL Then Conroe will come out and we will reach yet another plateau of uber l33tn3ss!
On the RAM, PQI, Mushkin, Corsair and OCZ are doing very well. There is a new one out every week it seems like. Go with what is performing the best. Follow RAM very closely in the RAM forum. Study it carefully. You've already OC'd so you know how important it is. The P5WD boards like speciffic RAM and timings. Check people's sigs too. You can tell by their OC and the timings they are running what is working well.
