im kinda tight on cash, and need best for the money, so realistically going from first to last on the list.
my friend has a single 5770, and can max basically any game (cept for crysis) and good resolution.
and would it be better for 2 5770s, or same priceish 1 5850. does crossfire really make that much of a difference, as long as not on HUGE resolution.
lastly... if im crossfiring, do i need 2 pci-expresses running at 16x, or two at 8x make much a difference.
tightish on cash,
Well in most case crossfired 5770 will beat out a 5850 or even a 5870, but with that there is also the disadvantage, of alot more heat, a bit more power draw, and of course lack of expandability, as the most you could go is x3 unless you have a crazy 4pci-e mobo. Also game that don't support crossfire ( which are very few at this point) will only be able to run as fast as one 5770 will take it.
As for 8x and 16x, you might see a slowdown in 8x but it'll only be a small one
i know they support it. but with two 5770s id be maxed out, so when i upgrade they'd be basically worthless. so wouldnt it be better with one 5850, and when i upgrade, get a second one? makes sense, right?
You could always add another 5770 =) Seriously though, I too would rather have 2 5850s but the amount of heat produced and power needed (which isn't that much actually) might require a complete overhaul of your system. It all depends if your system is capable of just slapping in another 5850...you might just have to buy another psu along with the additional video card.
