Sli Or Crossfire?

[supersaiyan]

i have a friend who is filthy rich. he wants to assemble a gaming rig and he has no budget boundaries. keeping this in mind and the products available in india i decided to get him pretty high end config. now the only problem is whether i should get a crossfire setup(x1900xtx powercolor) or a sli setup(gainward 7900gtx). on this basis i will also decide the mobo.

The SLI technology from nVidia is better because if u connect two graphics cards using SLI u will get very high performance...(though u can only link 2 graphics cards of the same model)...however if u go for ATI's crossfire (which claims linkage between ANY TWO ATi chipset cards) the two cards will perform at the level of the lower of the two cards, which obviously is not good! I read this in an IEEE magazine once...so i leave it upto u goku!

[deathvirus_me]

if he can afford to crossfire two X1900XTX .. then make sure he gets that ...

2 X1900XTX's in Crossfire is definitely better.

2 1900tx would be gr8!And better than 7900s...
What are the other components he is going for??

but i am getting two identical x1900xtx. so i don't think there would be any problem of lower performance. just imagine the power of that system. drooooolll

man! ur friend is gonna game like hell with dual-x1900xtx in crossfire...PLS TELL THE OTHER COMPONENTS OF HIS PC

[cyrux]

What about the nvida 7950 Gx2 ??

Can this card be used in sli mode ? That would make 4 7900GT...

[drvarunmehta]

No chance of getting that in India.

What would happen if some1 uses FireGL or Quadro FX for gaming purposes..i mean..they r meant for workstations,but what if they r used for gaming...r they better than x1900xtx and 7950x2 ?

[deathvirus_me]

Well ... SLi the 7950GX2 would be a nice idea ... but there is no official support for that yet ... and the performance increase from a single 7950GX2 is only about 3-4 fps .. seriously ..... u still don't have a CPU not bottlenecking a SLi setup .... yess even a FX62 is a SLi bottleneck ... so even that won't be a good CPU for a Sli'ed 7950GX2 ... not unless u can afford Two Dual Core Opteron 285's .. running with 16 MB of ram etc. etc ....

No no these gfx cards are specifically meant for workstations. nothing else. these gfx cards specialize in workstations like making movies,etc. not gaming.

umm....it shud be 16GB of RAM instead of 16 mb, lol...

Just for the info Asus, giagabyte and most of the other board manafacturers are providing nvidia 7950 gx2 @ $600 (27000) and msi is giving @ $550 (25000)

[drvarunmehta]

But those are US prices. In India these things will cost atleast 50% more.
