Quick CFX question

post #1 of 5
Thread Starter 
So I just found a really cheap 4770 somewhere on the nets and I was wondering if having two 512mb cards will give me a total of 1gb Vram. Price is really cheap and I'm really tempted, but it really won't be worth it if I'm still limited to 512mb.

CFX/SLI only uses the gpus to scale thus the memory is not added together. I repeat, 2 cards does not = double the memory.

The vram is mirrored between the two cards, so you stil only have 512 mb to play with
If you had one 512mb, and a 1gb card, you will loose 512mb of the 1gb card because it is mirrored.

512MB of VRAM is gonna kill the performance your HD5770s in CFX can deliver.

Maybe you wanna sell em and get 2x1GB?

Figured as much. Best route right now I guess will be a 6870 and then another one later.
