Long Post Warning:
I've been trying to research GPUs hardcore, I will be buying at least one next week (If my PC isn't a pile of rubble from the PSU accident). I stumbled across a forum post with something about Phenom IIs bottlenecking most of the newer cards, especially in crossfire. I think they said it was something to do with the CPU/NB and that you could solve it by overclocking that or something. Anyways, I have the 925 at 3.6 ghz stable and haven't touched the CPU/NB because I don't want to break anything (Ironic, because I blew up my psu...).
Would this heavily bottleneck say, a 6950/6970 or two 6870s? If so, would overclocking the CPU/NB help to alleviate? And if that's a yes, any tips?
I realize I'm probably going to get bottlenecking on my current processor with most any card I put in, and I know for a fact I'll be moving up to Dozer when they drop, so, it's not a big deal if I can't do anything about it. I think I've come close to settling on the 6950, a reference if I can find one on Amazon (I have 80 bucks store credit!), would it be better to go with a single 6870 for now then crossfire in a few weeks? I'm at 1680 x 1050, occasionally at 1920 x 1080 when I hook up to the TV.
Thanks for any help, I know I'm needy when it comes to this thread. Eventually I hope I can help out as much as you guys have helped me.
