is there more problems with SLI rather than performance? also gtx670 comparrison

[beasty6]

hey guys,

ive read that SLI causes a few annoying problems that eventurly gets people to go back to single gpu setups.

what is micro stuttering ? ive never had dual gpus so i dont know.

also i am going 670 SLI, i am doing it and i am also getting a 2560x1440 monitor, i also play a lot of skyrim and witcher 2 also bf3.

and am i right in saying SLI only uses the top cards VRAM?

so to help support those games at that res, shall i get a 4gb 670 for the top and then a 2gb version for the bottom for the extra power?

it sounds logical and more future proof to me but thought i would ask you guys for your opinions and expiernces with SLI or 670 SLI

looking at the KFA2 EX OC 4GB with the 2GB version

OR

the EVGA SuperClock and the EVGA GTX670 (looks the same as the 4GB version)
