So, I'm trying to build a horrible (see awesome) poison based magus.
So I gave him a +1 Toxic Virulent longsword.
Spoiler:
Toxic: Weapons with the toxic special ability reinforce the effects of applied poisons. The save DC of a poison applied to the weapon and delivered via an attack increases by 2. In addition, each time such a weapon strikes a target, there is a 25% chance that the poison dose is not expended in the attack and can be used to make an additional attack. A single dose of poison can be preserved by this property only once.
Virulent: A virulent weapon magically intensifies any poison it delivers. The saving throw DC of any poison applied to either a virulent weapon or any ammunition fired from it increases by a number equal to the weapon’s enhancement bonus. The duration of the poison increases by a number of rounds equal to the virulent weapon’s enhancement bonus.
(emphasis mine)
I also gave took spell blending to get Toxic Gift.

DESCRIPTION
You can cast this spell only if you are currently poisoned. You draw upon the poison in your body and duplicate its effects in the target, which is affected by the same poison you are, except it uses this spell’s DC instead of the poison’s normal DC. If you are affected by more than one poison, you must choose one to afflict upon the target.
And spellstrike...
Spoiler:
At 2nd level, whenever a magus casts a spell with a range of “touch” from the magus spell list, he can deliver the spell through any weapon he is wielding as part of a melee attack. Instead of the free melee touch attack normally allowed to deliver the spell, a magus can make one free melee attack with his weapon (at his highest base attack bonus) as part of casting this spell. If successful, this melee attack deals its normal damage as well as the effects of the spell. If the magus makes this attack in concert with spell combat, this melee attack takes all the penalties accrued by spell combat melee attacks. This attack uses the weapon’s critical range (20, 19–20, or 18–20 and modified by the keen weapon property or similar effects), but the spell effect only deals ×2 damage on a successful critical hit, while the weapon damage uses its own critical modifier.
All together for the question now, does the weapon boost the save dc of the spell? It is technically delivering poison since the spell has the poison descriptor, and the end result of the spell is poisoning someone. I'm trying to play a guy that chugs a rough poison at the start of a fight, wades in casting toxic gift and stabbing people. Having a sword that helps with that seems like the way to go.
