( This is the case I have now, I also have the 500 watt PSU that comes with it, but I do not know if it is powerful enough to run this system. Moreover, the PSU only has one power cable that fits the power supply of the video card, how do I get around this? With this case, should I worry about poor air flow or overheating? )
I am getting two of the HD4850 video cards to runin crossfire. The build all together costs $1,124, I did not include a case because I already have one. I am having trouble picking out a CPU as well. the Q9300 is fast but when it comes to over clocking can I save more money and get a different processor that will perform close in speed to the q9300?
