That's why i go MP (seriously) on my PC.
Consoles are way to overrated and pc rigs are way to underrated, yeah you put your blu-ray or dual layer dvd and boom! you are good to go in terms of easy search for some MP fun.
In PC well, it's another whole different story:
That's is tweaking the game to perfom better than expected or you can go *console mind wise* and buy the latest vga/micro/mobo/etc and think you can outperform older systems...
That's the fun of being a PC gamer and not a console one, being honest i bought PS3 for MGS 4 and not for the MP yeah i play COD or BF3 with some friend from time to time.
But i feel it's not my place in terms of gaming.
If i want hardcore stuff i have my gaming rig.
If i want *commodities* and insert only a disc to a tray and start playing i have the consoles or some games that never were released on PC.
