is it worth getting the t1 pvp weapon for pvp power boost or does the higher dps outweight pvp power in this case ? im asking because i heard pvp power is incredible strong and i dont want to waste conquest points
On my gear, pvp power is about 9% better than agility. So the pvp weapon with 4770 pvp power is like 5300 agility. However, when checking, my fully upgraded rf taoren gun (i491) gives me about 2.3% more dps than my un-upgraded pvp weapon (i470). Your heroic version would be much better.
The t1 PvP weapon gives you roughly 20% more PvP power, meaning you deal 20% flat dmg to other player. Taking into consideration you should upgrade it asap and it's needed for t2 (and it has resilience on it) I see not a single reason why you should use a PvE weapon whatsoever.
