will two gtx 660s in sli last two or more years playing new games on at least medium settings? would sli gtx 660tis be worth it for an extra 150-200 bucks? and what is scaling, im new to this and i dont know what that means
 
Solution

Get the 670, in 1-2 years you can add another 670.
scaling is essentially of how much additional performance you get out of a card after one or more is added. I dont think theres any setup that scales to 200%(as if you doubled your gpu power) as crossfire/sli will bring a bit of problems and communications together in such way that the actual outcome will be a bit less than 2x performance.

On med setting yea easy
 
with 2 gpus you have:


Games that are incompatible with sli/crossfire
More Heat
Higher Power Consumption
Microstuttering in 2 card builds(not as existant in 3 cards)

normally, sli/crossfire should not be used straight away. It should mainly be an option in the future when you want more performance later with a reduced cost.


edit: microstuttering is when fps dips up and down rapidly which causes funny framerate speeds which affects visual performance at times.

Diablo 3 for example without v-sync

the power consumption is not an issue and considering im coming from a xbox 360 i dont think stuttering will be noticable. and what are some games that arnt compatible with sli? i wont be going sli straight away, i probly get a second card 1-3 months after i buy my system

Since when does saying "any" problems exclude metro 2033?

Seriously, go for a single gpu solution. GTX 670 is way enough to play medium for at least two years. Probably better than that even, actually. You're asking for problems by going SLi.
 


what is your gaming resolution? what kind of frame rates are acceptable to you? if you do willing to turn down the setting down to medium so you can get minimum of 30 frame rates per second then 2 660s will going to last you for quite sometime even on 1080p. my bet? maybe i'd say that such setup with such requirement may last you more than 3 years for majority of the games available.
 



to be fair, metro rejects most cards on heavy resolutions and quality

ill will be playing at 1080p, and anything above 40 frames is acceptable to me. ill will probly upgrade in 1.5-2 years anyway but i just wanted to be sure it would last and be not completely outdated next generation
