Fastest way to get rich in Grand Theft Auto 4 – Episodes of Liberty city: The ballad of Gay Tony Singleplayer

You miss out on the perks, like the weapon delivery you mention. Also there are Achievements & or Trophies depending on what platform you're playing on.

After that, I do not believe so. I think (but need to verify) that as you ignore them how much they like you will drop, and if it drops too low they won't be your friend anymore if you change your mind and want their friendship after all.

Still, my thought would be, on a second playthrough, don't worry about the ones you don't care about.

Depends on the full configuration of your computer and the settings on which you want to play GTA IV.

The results in the two sites differ because both benchmarks use different settings, the one at Tom's Hardware uses:

1280x1024 (Medium settings, Vsync off)

while the one on behardware:

Once again all the settings were pushed to a maximum, with the exception of the textures so as not to exceed available video memory, all at a res of 800x600.

I think any of the two family of processors can handle the game and the final recommendation is conditioned by what type of gamer are you and what type of budget do you have.

• If you are an avid gamer then the i5 is your partner, this processor will run games smoothly for years to come.

• If you have a tight budget and are not so keen on spending your time gaming then the i3 is for you.

It's up to you what you choose, but with medium settings both processor hold. Also as an additional information GTA IV is one of the games that is not highly optimized so any excessive use of settings will severely punish your FPS see behardware benchmark.
