I didn't know what category to put this in, but hopefully people will read it anyway. I've been looking on ibuypower.com, and I really don't know what I'm doing when I'm choosing the internal parts. The problem is, when someone that knows what they're doing helps me, it ends up being like 1,300 USD, when a commentator I know paid $800 for his, and it runs BF3 on high-ultra. Any help?
Always better to gather and assemble the PC yourself. If you pick it up you minus postage (remember a PC can be up to 20kg), the service cost of putting it together, and just the general mark-up that pre-built systems come with. Also when you build it yourself you have the freedom to pick any part you want and find cheaper prices anywhere, and after that much research you know the components off the top of your head, much more familiar with the machine.
Plus its amazing when you hit the power button and it all works, gives you free reign to scream "Its Alive!" and cackle like a mad person ( or is that just me?).
Hitting up the CyberpoweredPC site a suitable BF3 system is $869 w/o monitor or shipping
for BF3 you need a quad core CPU and at least a GTX 560 to play at 1080p in 64 multi-player on Ultra.
You might get by with a i3 2120 Dual core but you could experience some framing on certain maps.
