Ok so say I do switch to a Q6600 instead of the AMD. Will I run into any compatibility problems running an intel instead of an AMD? Also... Is this build decent, meaning will it do what I want it to without bottlenecking anywhere? Or should I just scrap everything and start from scratch? I'm assuming I could get a computer comparable to this for around $1100 shipped, even if I do have to assemble it myself.
Also, one last question regarding the video cards... I'm correct in thinking that crossfire 4850s will outperform a single 4870, right? Or should I scrap the video cards also and go with an nVidia something.
