Thx for all of the great info. an advice. Cost really isn't a main factor with this 1st APU based build, it's more for testing, performance and gaining experience an time with the chipset/component combination. Will test with just 6800, crossfire with 6570 (already have several) and crossfire with 7750. I would hope the drivers will improve as time goes on, as well as AMD finally making the 7000 series GPU's a mainstay for x-fire. I can't see them continuing with the 6670 forever, or for much longer at that.
That's just a guess though. I would also like to test configurations and performance using the Athlon II X4 750K FM2 cpu as well. I have always loved them old Athlons (mainly the Propus and especially the Reagor) and would hope to see the Trinity version not ruin it's rep.
For like 80 bucks, I can get a quad core 3.4ghz ath and pair it up with the 6570, 7750, and a 7850 and 6950 that I have now. Later I can figure out if it's cost-efficient and good performance by going with middle of the road components, albeit well built ones. I just have a gut feeling that this combined technology will be the wave of the future eventually putting the old cpu/gpu/mobo the way of the transistor radio...lol
Thanks again! And hopefully we'll see those sweet Sniper FM2+ boards really soon!!
