What are your computers specs? With all those blue LEDs you've got to have a fast system.
it was fast when i got it in 2009, it's only had two upgrades since then (an extra 2gb of ram and the gtx 460)
i've got a dual core AMD athlon 240 CPU running ~2.8GHz with 4GB of RAM
my graphics card is a nvidia geforce gtx 460
it runs most of my games with little trouble, but i can't really livestream anything because my cpu is really kind of awful
i also can't run a decent minecraft server anymore ever since it updated to 1.6.2, i used to be able to hold up to 4 people with no lag but now i can barely handle one person
