question for you SLi techies

:hi2: evenin'yoall

i've just been playing call of duty 2 and noticed a considerable fps drop between directx7 vs directx9 video settings with directx7 settings the frame rate was sync perfect at 75fps but when i changed it to directx10 the fps drops to an average of 45fps

will getting sli (a second gpu) boost the fps to 60+ and my second question does it have to be the exact same gpu i have now to work with sli

i currently have 1x 7800GT, i was hoping to get 7800GTX or 7900GT(X)


thanks for your help any reply will be appreachated

 

You will Need the EXACT same GPU (Make and Model i belive), other than than i cant help :/

sorry!

 

wow, thats not cool stuff runs way slower on DX10

 

oops i meant DirectX9 lol

thanks for reply guys

 

DX9 has a lot more things that need to be processed than with DX7. Essentially better eye candy and more detailed renderings.

 

Essentially you need to have the same GPU for SLI but you dont need to get it from the same vendor.
