If you buy a decent GTX 670 it has either the PCB from the 680 or a custom built one with excellent quality.
That is true. The 7970 Reference is definitely more robust. However, my brother just picked up an Asus GTX670 DC2, and it's awesome. It's whisper quiet. It's a really nice card, and the build quality is top notch.If you buy a decent GTX 670 it has either the PCB from the 680 or a custom built one with excellent quality.
You don't say "reported" if you've reported someone. You just report it and leave it at that. Saying "reported" counts as provocation and in itself is an act worth reporting IMO, not that that's what I'll do, just pointing it out.
Sapphire 7950 950 MHz edition and ran on 12.8 and currently 12.10. Battlefield 3 and Borderlands 2 run like a dream, Diablo III and Dota 2 not so much. Diablo III is playable after some tweaking but Dota 2 is downright unplayable. Considering Dota 2 is my main game, it's kind of a bummer and makes me regret upgrading a bit.No info about what AMD cards you have or what drivers your using.
what are the cons of overclocking?If you're overclocking, the 7950 is a much better buy. Using the same site: http://www.directcanada.com/products/?sku=11830BD3894&vpn=GV-R795WF3-3GD&manufacture=GIGABYTE . The GTX 670 will be faster at stock, but once both cards are overclocked they'll be neck-and-neck. That said, the GTX 670 wouldn't be worth the extra $60. I think in either case getting the Gigabyte Windforce 3 is a great choice.
As far as upgrading goes, when you need more power just grab whatever newest GPU is out then. Multi-GPU is rarely a good idea and it's even rarer that it's a necessity.
