I think either will work great. You won't lose that much top end with 4.10's. You can still get up to high mphs, just might have to shift into 5th to do it.

I am considering changing my gears so I can get better take-off. Should I go with 3:73 or 4:10? I heard I would lose a lot of top end speed with 4:10s
The only thing you might lose is a coulple of MPG`s, and if you`re worried about that you shouldn`t be doing those kinds of mods. If you want to play you have to pay.

Your car will be gearing limited to 176mph with 4.10's which doesn't matter much because without a ton of power and aero work it won't go glose to that fast anyway.
You have the ability to answer the question of what gear ratio will work best for you. Don't simply listen to some dork that says you "need X.XX gear because they ROCK!" For all you know they are borderline brain dead. Just because they don't mind driving around with the motor spinning to the moon doesn't mean you won't.
This is the most important information you need before making your own choice based on your situation:
What RPM’s do you want to be cruising down the freeway at and at what speed. Think about that hard, and go drive the car. Drive it for 2 miles at 3,000rpm…..it will most likely drive you crazy. If it does, you want to make sure you don’t get a gear that will put you in that range. I have mine set up to run at 2400rpm’s@80mph. I wouldn’t want to spin it any higher than that even if it costs me a bit of acceleration.
Depending on what the height of your tires have I'll bet you will want 3.55's or 3.73's to get a comfortable cruising RPM.
I run a 3.55 and couldn't imagine wanting to gear my car shorter than it is. I do have a screw blower though. 1st gear is worthless, I just punch it and have to shift right away and 2nd gear will haze the tires even though I have some seriously sticky rubber. Shorter gearing wouldn't get me going any faster....faster. It could possibly even slow me down.
Even if you don't have a blower but have stock-ish tires (high performance, all season about 235-245mm wide) you will still light the tires up something good in first and have to go for second super fast which makes that gear borderline useless. You will still lightly spin the tires most of the way through second too (if you make the 1-2nd gear shift fast) which lessens the effectiveness of that gear too. Which will slow you down.
When I had my stock 3.31's and stock Pirelli tires (about 75 miles) I could SPIN the tires all the way through 2nd gear if I wanted too.
Use this gearing calculator. It will help you pick a gear for your situation. Use the # .71 for the auto trans ratio and .68 for the 5 speed. You will also need to measure the height of your rear tire at the right pressure sitting on the ground. You can keep firing numbers in till you find the gear that gets you the cruising RPM that you are looking for.

Squidd is right,but in my case I was driving way too fast on the highway,and I was looking for better 60` times.4.10`s slowed me down on the highway,haven`t made it back to the track to see if my 60` times got better.He`s running 2400 @80 mph,I`m doing 65 mph @ around 2400 RPM.It all dependes what you want.Lower gear doesn`t always get better accelleration if you`re spinning the tires,there`s more to it than that.I love the way my car is geared for the way I drive and what I`m looking for, You have to make that decision for yourself.

I had 4.10s in my 08 GT. They were a lot of fun but got old in a daily driver. (85 mph=3000 rpm) If it's a daily driver, I'd probably get 3.73s. I have some ordered for my 09. Should still help a lot over the stock 3.31s.
Alright thanks for all the advice. I might just go with 3:73 just to bump it up from stock. I dont want the engine screamin on a normal drive through town haha
Considering changing my gears. 
all motor now.Don't ask.
, and if you`re worried about that you shouldn`t be doing those kinds of mods. If you want to play you have to pay

..thanks for the advice guys
