4870's crossfire worth it?

post #1 of 44
Thread Starter 
Hey guys,

I just bought 2 brand new 512mb Asus 4870s for my sig rig. I'm running all of my games on 1920X1200 on a 24" monitor. I've just done some looking around and it doesn't really seem like crossfire 4870s is even worth it. It many cases a single 4870 gets better FPS at 1920X1200 than 4870s in Xfire!!!!!!!

I mostly play COD4, Crysis, Fallout 3 (ftw), and I am going to be getting L4D and GOW for pc for xmas. Is it worth having the crossfire if I'm going to be playing these games in my sig rig because if it's not, I will sell the second 4870 and get some dough back? (I'm going to be selling my sig rig in a year so i can build a new rig from scratch for college)

I think your board isn't full XFIRE. Its only 8x 8x instead of 16x 16x.

I would think 2 4870 in xfire would be better than 1 4870 but also depends on the drivers. Some people were or are having issues with xfire in certain games.

which ones? I know for sure that 1 4870 is a craploadbetter than a 4870. but is it worth a second 4870. Also 8x xfire mode, does that lower my fps by a lot?

8x only means your not fully xfire... I could be wrong. Your xfired but not taking full advantage of xfire and your cards.

I'm looking at getting the same board you have and I think I will end up going 4870x2 or 1GB 4870.
