Question about SLI and power consumption

Doing SLI with an outdated performance GPU is NEVER EVER a good idea. Just NEVER.
SLI brings more problems than it solves and an outdated GPU will not give you the performance boost you may want.

To name a few reasons:

- Extended power only usable when the game has an SLI profile, meaning newer games without it will not be playable at first
- Missing features of newer cards will drag you down
- Inefficient power usage
- Not nearly enough VRAM. You have to considered that even though the power doubles, your VRAM does not. A card with the power of 2x570 and just 1.2GB VRAM is a joke

The only time I can recommnd any form of SLI/CF is when the power of the currently strongest GPU on the market is not enough and you need multiples of that.

It actually depends on the need. For compute, SLI/CF are fantastic. If it's strictly for gaming, it will be for bragging rights at most.

I'd love to see someone bragging about getting a second 570 today^^

I can only laugh at people who build SLI/CF with less than top of the line GPUs. For gaming of course. That's like taping 2VW Golfs together and pretending it's a Ferrari.
