So ive upgraded my rig from an 955be to a 2500k and i seem to be at a gpu bottleneck in any game thats gpu heavy i get 50-75% on cpu usage and 100% gpu

im wondering if my 6870 single isnt enough will crossfire even help?
or will i just have 2 6870s bottlenecked

I ask this casue im pretty sure they dont share load. correct?

They just run the same things on both cards?

Im not really sure how it works at any rate if im going to be bottlenecking still with cf 6870s whats a good upgrade?

Even the 6970 sees very little fps improvement for the money. +15 fps top end most games? so is there just no cards out strong enough to make use of
the cpus?

Should i be waiting for the next round of gpu releases?

Also because of my 120hz display i like my average framerate to be in the 90s+ so even tho crysis 2 on ultra with one card runs good at ~40 fps id turn stuff down just to get the 70 on high but id like to not have to.

ideas? and info on how crossfire actually works be sweet!

Thanks in advance

First its normal to have full load on gpu and only half load on the CPU for games. Because the CPU really only handles hard body physics but the GPU has to handle all the lighting and shading plus the soft body physics. Second it depends on the game, some games will support Crossfire/sli and some don't. If it does you will see about a 60% performance boost if the game does not support it you will no gain and in some cases it will make it worse. When properly functioning crossfire/sli the two cards share the load. If you have two of the same cards it should be fairly symmetric load distribution with some bias toward the primary. if they are different i.e. a 6870 + 6850 the loads should be biased toward the faster card.

so my bottle neck should go away with games that support crossfire 6870s?

Plus, not all games will use all four cores of your processor.

i understand that most agmes that need the juice support cf and at least 2 cores so im ok with that just wanna be sure when a game wants to stretch its legs it can
