First reflow gpu chip.if display comes just for testing purpose reball it.otherwise chances are you have to replace it.

Don't do reflow at all, don't stress the chip more than you need, reflow will work in minor cases even if the chip could work after reball.
Just try reball, if it will not work, try change for other chip, that's it

I mentioned it before and I will again. If the chipset is not shorted most of the times it is good for a reball. The main problem is not the chipset but a deformed board due to long exposure of board and plastics that support it to excessive heat.
A lot of times I come across even and to deformed chipsets.

In my opinion any machine around or above 1000$ will serve you well.

To be honest, if you are into some practice DIY machine can be better and more long lasting then cheap IRDA machines, just my 2 cents.

P.S: Doing reballs with Preheater and hotair station 2 years and can do it 100% right every time .
