Siiiigh lol its like which religión is the right one...
I have 2 xfx 6950 2gb cndc models and they're great. But if the sapphire toxic had been available when I bought these I would have went with those no doubt.
Customer service at xfx isn't the greatest either. There has been times I couldn't get any help and had to turn to the egg... Fortunately newegg is great... Have always gotten their help even past their deadlines. There's even a few cases they've went out of their way and called me. Moral: can't speak for sapphire support but xfx's sucks!
but if i use the 2G card first(toxic) does it matter much if you use a cheaper unlocked 1G card to crossXire?
no, you don't mix 1gig cards and 2gig cards. If you have aspirations of running 3 monitors 1gig of video ram is not enough. You need cards with 2gigs. cross-firing 2 - 1gig cards does not give you 2gigs of memory. It's still only one.
Well ill stick with the 2G saphire toxics 6950's as my choice of crossfire setup, when i connect my 3 27in monitors, do need to buy an active adapter or can i hook two monitors up to one card and the other monitor up to the 2 card via hdmi
