This is what I find to be the best bang for buck for me , I read reviews and found Maingear to be the best dealership.

This is my first system that I buy in the USA and i wont be staying here long , so I want to use the time and grab a badass system to take home, ( its alot more expensive where I come from) , I have very little experience with computer hardware except for what I have Read this year.

I would love some suggestions or opinions on this

MY MAXIMUM budget is 3000$ , anything below is nice.

I am not in any rush to buy it , but I will be going back home this summer so would you recommend waiting for the new ivy-bridge cpu?

I am running 2 monitors , 1 32" hd t , via hdmi cable and benq v2420 , might be changing my tv out for 27" lcd gaming monitor

Thank you very much
