Will these components work together or will I have a problem with any of them interacting? Thanks for your time and help.

^1+. Nik_I got it right. one thing i would like to say though, i would suggest getting ether the ATI 4870 or the EVGA GTX 260 core 216. they perform about the same, and will both blow the 9800GTX+ out of the water. i have been rather disappointed with the 9800GTX+.

Is there a reason for going SLI instead of crossfire ? Cost/performance of ATI graphics and the intel P45 X38/X48 usually make it a cheaper and more stable choice. Also, replace that Kingwin, just no reason to use a poor power supply when so many others will fit your budget and work better.
