Hi, I currently run an Ati 5850, and I love it! I can run every game, most of which I can totally max out. However, I'm feeling the tug to go for crossfire and I was wondering if it is really worth it. I have around $200 saved up currently, and I'd expect to have the $300 by the middle of June. I have a 600 watt Power supply which meets the minimum requirements, but I was still thinking of buying another one. So will the performance I will get from Crossfire be worth $400? Thanks.
