I don't reeally like the FX 9 series, it's almost like OC an FX 8350. I'm planing to upgrade to intel but i'm waiting to be less pricey where i live, maybe an i7 4790 or i5 660K but in 5 or 6 moths from now. I know the R9 390 is better than the GTX 970 but is not enough for the difference i have to pay.
That's why i want to know if i can make SLi in my current sistem for a few months
