yogurt_21you know I wouldn't be surprised if this card got close to the performance of the 6990, maybe even matched ti for a lower price and power power consumption.

Jonap_1stcomparing between recently 6870 crossfire and 6990 benchmarks especially on higher resolution, i bet it will be 10 - 20% slower since every dual gpu cards had to reduce the core clock..

crazyeyesreaperactually 6990 didnt technically reduce clocks they still offer 6970 speeds via a bios switch,

only dual gpus on the AMD / ATi side that didnt come at proper clocks was the 5970

4850x2 4870x2 6990 all have proper speeds out of box or with no more then a switch to flick,

not sure on the 3870x2 but i believe it had 3870 clocks as well im to lazy to look

where as Nvidias dual gpu cards tend to be underclocked as nvidia has in most situations had the higher TDP and power requirment except when comparing the 295 to the 4870x2

overall i expect at 1680x1050 the 6870x2 would be 5% -10% slower then a 6990 at 1920x1200 i would expect the gap to widen to 15-20% at 2560x1600 it would probably hit 25% it would really vary between games tho and cpu, as 6870x2 is less likely to be cpu limited then a 6990

yogurt_21crazy pretty much covered this but when it comes to lower power gpu's, the duals actually have the exact same clocks. EVGA's gtx 460 dual is a testament to this.

if they run full speed clocks the max gap would be at 2560x1600 and would be ~15%
so your 1680x1050 prediciton is likely dead on, the taper is just likley to be abit slower from there.

n-sterI don't see why 2GB per GPU is so important for everyone.... Unless you game with eyeinfinity, I do not the huge urge of having so much VRAM

6870x2 is smart.... my 6870 CFX is pretty good. beats even 5870s CFX and 5970. Not that close to 6990 though as someone else mentioned. pretty far from it really.

crazyeyesreaperit does more then nothing if you use the right games,

Oblivion Fallout 3 and New Vegas all easily use more then 1 gb of vram, with mods and graphics tweaks

example with my ini files and mod load out 5850 crossfire would do 40 outside, with my edits to shadow properities the avg frame rate dropped to 1fps due to running out of vram, a single 6970 offers 45-65fps with those same settings

metro 2033 at 1920x1200 hits 1450-1500mb easily

theres other games currently few and far between to be sure, but it dosent make them usless,

6950 1gb vs 6950 2gb at $20 difference id take the 2gb

6870 crossfire is damn good and a 6870x2 would make alot of sense, but considering its performance lvl would be higher then a 580 or 5970 and higher still then a 6970 it would make sense to have that extra ram because in effect it is a gpu ment for HIGHER RESOLUTIONS, you dont take a knife to a gun fight and you dont take low ram multi gpu setups to high resolution demanding games. its why at 1920x1200 and 2560x1600 the 5970 loses to a GTX 580 because v ram does tend to become a limiting factor, now if im buying a GPU today to play newer games tomorrow, you dont want good enough today shitty tomorrow or maybe you do i dont know im not you lol.

LAN_deRf_HAWell if we're making a list don't forget GTA. IV goes up to 1600mbs maxed. The expansions reduced that to about 1280 so it fits perfectly in for a 470/570. Mods have aided its shelf-life.
