HD 6950 2gb crossfire with 1gb?

[Aimbayya]

Hello everyone,

I recently got a XFX HD 6950 2GB, i was thinking about Crossfire when i have the money.
What difference would it make when i crossfire it with a HD 6950 1GB vs a 2GB ?

performance wise or will it only affect resolution?

thanks

It will cause the 2GB card to use only 1GB instead, due to how crossfire and sli work.

[Aimbayya]

thats what i thought, but the performance will still be better if i play at lower resolution right?
the 2GB will get bottleneck by the 1Gb if i play games at a higher resolution.

for example battlefield 3

Yeah for the most part it'll only really start to bottleneck at higher resolutions and/or high levels of AA.

[Arinoth]

Also depends on what is in the rest of your system too, if you're running an older 775 you may hit a bottleneck on higher resolutions or high AA either way.

will be running a i7 920 co stepping
thanks for the help =D

i will post my system specs when i get everything together and up and running.

You would be better off getting another 2gb card, and do make sure you are running triple channel so you are less likely to be running into lack of memory/memory bottlenecks :)

thats probably what i`ll end up doing, getting another 2gb when i have the cash

For sure, if you must get another card make sure it is a 2GB card!
