SLi question

[computerbuildin]

so im new to this, and I had a SLi question. So im getting the asus GTX 560, NON TI version. So far I will only have 1, but maybe a few months or so later im going to buy the same one and dual SLi it, now im not sure how this works, is it basically just plug and play with the bridge and the power, and I just keep my one hdmi plugged into my original?

yep. you might have to re-install the driver, then enable sli in the controls. i would make sure the motherboard is set to activate pci-e 1 first.

ok thanks and also, is SLi worth like 200$ more? cause one of these GPU'S are 200.. and I wanted to know if it would be worth it, and the performance is basically just x2 right?

What resolution are you playing at?

you'll never get a 100% increase with another card, and less with 3 and 4 cards. you should expect something like 50-80% performance improvement, depending on the game. you might also run into problems, like micro-stutter (instead of pictures being drawn evenly 1..2..1..2 they are uneven 1.2....1.2....1.2)

Before I delved into SLI I was concerned about micro stutter. I am picky when it comes to frame rates. But I am happy to report that these two 460's in SLI are smooth as butter. Very happy with SLI.

Now, granted, I still consider requireing a profile for it to work a drawback, but my thoughts were this: Mostly only Triple AAA titles up the ante in the graphics department. Both AMD and nVidia never skimp when it comes to a Triple AAA title for support. Therfore, if a game is graphically demanding, it will have a decent profile. If it isn't demanding, 1 card will be enough anyway. So... Yeah, that is how I feel.

just saying
best practice moving to sli could be -if or not you have issues
-reset mb bios if new\ or \ update
-reinstall new chipset drivers
-clean install vid drivers reboot
- set sli in nvcp reboot
- mostly 99% of sli installs are plug and play but the 1% could show up in strange ways and you might need to do the ' best practice' any ways.

Assumeing your motherboard supports SLI (if not then getting a second is pointless), then some performance is expected. 100% is not going to happen and on some games going slower can occur (rarer). Though it still holds that most performance from going SLI occurs at higher resolutions. If running a low one, SLI has less effected all else being equal.
