These appear to be the obvious range of choices:
I had a very hard job trying to determine how to narrow it down further???
But then I noticed the listed bus speed of some seemed low. While I only have a lowly Athlon X2 now, I intended to in the near future upgrade it to a a higher end AM3+ FX CPU. They go at 5,200 MT/s so this seems to rule out all of the above except these two:
Is there any obvious reason why I should choose one over the other? It seems to me the only real choice I need to make now is having the option of a future expansion to 32gigs of RAM or instead if having potentially Crossfire is more important to me. (I'm leaning towards the former of 32gigs being a more likely upgrade for me than Crossfire, maybe)
(that was a mission and a half researching and writing this on my phone! Can't wait to get my computer back...)
