Which is the most preferrable configuration one(1) XFX 5870 or two(2) XFX 5770. I have a ati xfx 5770 in my 3gig dual core system with 4gigs of ddr2 memory. Would it be better to crossfire a second 5770 or upgrade to the 5870.
I prefer to use a single powerful card over two "linked" cards. Therefore, I would go with the HD 5870. However, that is the more expensive option; a new HD 5770 can be bought for $100 - $110 after rebates.
