sli or not to sli

[m54]

In the process of upgrading my rig, I'm using a Asus P7P55D - E Pro mother board and a Gainwood Phantom GTX560Ti. I am wondering if buying a second graphics card of the same make and running it on sli would make a big difference to performance as it would be going from one graphics card running x 16 times to 2 running x 8. 2 x 8 is confusing me. Any advice and explanation of single at x16 or dual at x8 / x8 mode.

Hi and welcome to the forum.

Firstly you don't need another GTX 560Ti of the same make.

If the card is the 1GB version then all you need is another 1GB GTX 560Ti from any manufacturer.

Secondly don't worry about x16 and x8. Running at x8/x8 results in a very small reduction in performance compared to x16/x16.

+1 and you'll get a very nice performance increase with 2 560Ti's I have the same motherboard running 5850 in CF and the two PCI-E slots are running at 8x
