Aye, you'll cap out int pretty quickly, but sta, the other important stat to worry about, will be difficult to cap even at the higher levels. I think I'm like +100 int or something over my max int, but my sta is still 9 points below the max, that's with quite a bit of +20-30 to all stat items. I think the consensus is that int is the more important but you'll max this early, and therefore you'll benefit with stamina at the later stages. So, ask yourself, would you rather have it easy in the beginning or have that slight advantage during the middle to end game which will take MUCH longer to get through?
I'd go with stamina, I think 95% of the time I've died, I've had a lot of mana left(over 50%), but no health of course haha.
