To First Person Shooter fans, this argument is one of the most heated arguments for gamers.
Fanboys vs. Fanboys, we see it all over our forums, YouTube videos and real-life discussion.. But, which is better?

Well, you can't just say a game is 'better' than another just because you are a fanboy, you must discuss both games, and see the differences. The good and the bad.

Let's start with Call of Duty Elite and Battlelog.

CoD Elite is the place for Modern Warfare 3. Connect with friends, compete for real prizes, "stratergize" the game, etc.
It's the heart for true CoD fans. With a 'low' fee of $50 a year, you can enjoy your life as an Elite CoD player.
Personally, I really like the design for this website. It's slick, and modern. But what don't I like? The cost. $50 a year? I find it just another way for them to scab money. It's a community place, it should be free.

Now to Battlelog.... It's like Facebook for Battlefield 3, It is the heart of BF3. Here is where you connect to servers, make friends, show off your stats and all that stuff.
Yes, it is free. Why? Well, you see, this website IS the main part of Battlefield 3. They took the Multiplayer menu out of Battlefield 3 and have placed it here, to gather more players to their website. The downside? This website plays as the menu for the game. It has downed many of us fans, because the menu in-game was better. Mainly because we didn't have to alt TAB such a hard game for a PC.

Also, just a quick discussion on the specs of PC:

Modern Warfare 3:
CPU: Core 2 Duo 2.4 GHz / Athlon 64 X2 4400+
Grahpic: Geforece 8800+ / Radeon X1800 Series
RAM: 2GB+ (4GB rec.)
DirectX: 9

This game will be very easy to run on high, as the requirements are low as it can gather the specs for Modern Warfare 2. (Also, I am not sure if these are the REAL specs)

Battlefield 3:
Minimum System Requirements
Processor: 2 GHz Dual Core (Core 2 Duo 2.4 GHZ or Althon X2 2.7 GHz)

Have a look at the Ultra. Basically, YOU NEED 64-BIT. Eh, many of us have it. Also, The GPU and CPU... Those are very hardcore things right there. You are going to need a high-end computer for Ultra... Luckily I make the test.

Next time:
