currently using GT avalanche 2
with suntour XCR dual coil fork.
thinking of changing to XTC team frame with rockshox SID race dual air fork.
but as a student, i don't have enough money to get both at once. decided to get them 1 by 1
since both is around the same price,
which one should i get first?
and which one make my bike lighter?

in my opinion is the fork
upgrading from a coil fork to a dual air fork makes more difference than upgrading from aluminium frame to aluminium frame.
the fork is the part that absorb bumb
which frame is just the geometry. xtc and avalanche have almost the same geometry
so, fork makes more difference. i believe that your fork is at least 2kg. sid race is about 1.4kg
u saved AT LEAST 600grams.

As the question is posed, I'd get the fork first. The SID is a good short travel fork that is popular with XC racing crowd because it is so light. Going from a coil design to an air shock will have a big impact on the feel of the bike and I am sure you'll save a good bit of weight, as well.
However, pound for pound, ounce for ounce, cutting rotational weight is more important than cutting fixed weight. Reduced rotational weight allows you to accelerate the wheels more quickly and gives you more of a feeling of lightness and nimbleness. Generally, cutting rotational weight has about 3 times the effect of cutting fixed weight.
So, if you don't already have light weight tires, get some narrow, light, low knob tires like the Specialized Fast Track Pro (LK). They aren't too good in mud, but they are light and super fast on all other surfaces.
From that point on, you need to do you calculations on every other part to see where the biggest payoff is. For example, you may want to compare the effect of a lighter wheelset to lighter handlebars. If the handlebars will save more than 3 times the weight of a lighter wheelset, buy the handlebars. (Of course, you also have to look at your budget, but money is usually of no consequence to weight weenies.)
I like going to the light-bikes.com website to check out what other people are putting on their bikes to make them light. Here is the link:

Hope this helps.

I would look first at a lighter pair of tires. Probably a lot cheaper and it's on the rotational mass.
Of the two components you mentioned, I think that the fork will be a more significant change than the frame. Both in the weight, and how you will feel the bike.

1. Rotating mass has the most effect on climbing and acceleration. Wheels, tires, cranks, pedals, even shoes.
2. Work on your motor. That will have more impact than anything you do to the bike.

Titanium frame is strong than steel but lighter than carbon fiber and is available from Seven.

Concentrate on the weight of your wheel rims, tires, and tubes. It's the rotational weight that you want to take care of first.

frame first... it's what holds everything else.
