Well, I guess I'm going to have to be the party crasher here. Why upgrade? That 8400 is still one of the best duals around. Heck, Nehalem didn't really improve on the C2D's IPC, it just added Hyperthreading, and an integrated memory controller (although the controller on the duals is worse than the lga775's) Crank that 8400 to 4ghz+ and I'd be surprised if you ran into problems with any game. It's the cheapest solution, and there's good stuff coming up in the near future. USB3 will make external storage 10x easier, and we're looking at a full shift to 32nm in he next 6 months or so. Plus, Bulldozer will hopefully make AMD competitive in the high end space, and finally force Intel to drop it's prices (C'mon the 920 has been at $280 for 15 months, that's ridiculous) The longer that you can wait between upgrades the better off you are.
I cannot get past 3.6ghz stable which did little to nothing to help frame rate anyway.
I could probably OC the Penem 2 to equal a stock I7 in games. BE means its unlocked right? might be easier if so.
Anandtechs bencies show it only a few frames more.
My current has newer games run below 30fps. Stalker COP runs at 16-23 fps. Its holding my 280gtx up pretty bad in most newer games. I play max settings.
Anandtech article says this:
The Phenom II X4 965 does very well, inching ahead of the Q9550 and basically performing the same as the Core i7 920. Not bad at all
I could wait a little longer sure, but that never changes, theres always something better around the corner. Even if i spent $3000 today on top end stuff, it still won't be worth a crap in 4 years. I'm looking at 1-2 years tops before upgrading again, by that time, 8 core/16 threads may be more mainstream.
Seems to me anyway, from a price standpoint, that incremental mainstream upgrades yields better long term performance results than blowing a 5 year budget all at once. Like i could blow $2000 right now, but i'd rather spread it out. I'm thikning i'll go with Phenom 2 unless someone makes a valid enough point to show why i should not.
Thanks for everyones suggestions, very helpfull. I'm gonna think about it some more so i'll take all advice i can get. I also need advice on DDr3 or not. I'm getting new ram regardless though.
