It will primarily be used for gaming titles like Crysis, Modern Warfare, Fallout 3...Max Res. 1920X1080 two monitors 19" and 32", Moviemaker is my editing software need to get some thing a little more adept but it serves its purpose for me.
Looking to Crossfire for first time on this board. Also, would like suggestions on best RAM like Should I use 1866MHz Ram or just stick with 1333MHz?
Budget is around $600.00 for RAM, CPU, Vid. Cards, and a HDD...I have the rest of the system: Antec 900 case, OCZ 550-watt PSU, Win 7 64-BIT
Focus on the gaming, then, and just live with whatever HD-edit performance you get.
Your gaming requirements would rate a stringency of "8.7" out of 10 (on my scale) and, so, I would recommend ONE SINGLE 5870 (or 5850) ... to start with. A single 5870 will almost peg hi-rez with "all-on" or "most-on".
NOTE: Pretty sure the 5970 uses TWO PCIe 6(+2)-Pin PWR connectors (each). ... This PSU has 4 of them.

This OCZ 80+ Gold is an excellent power supply with very good reviews. It is, however, expensive.
For 2x 5870 or 2x 5970, an 850 W power supply should be adequate, 1000 probably isn't necessary.
As Alvin mentions, 1333 MHz or 1600 MHz CAS 7 RAM is the current sweet spot. The G.Skill kit he linked is good value.
However...I have a question. You say:

A 5870 starts at $400 (and the 5970 starts at $700), leaving you not enough room in your budget for, well, anything other than a hard drive. You say you're waiting for the Phenom II X6, which is rumored to be between $200-300.
Total = $1450, not counting CPU (which is still unreleased and pricing is still speculative) or storage hard drive
Alternatively, you could put two 5870s in there for about $120 more. If you need to drop some money, you could either drop one of the 4 GB RAM kits or move to CAS 7 RAM, probably the kit Alvin linked earlier at $115/4 GB.
Again, be aware that your 550 W PSU is not going to be sufficient for Crossfiring 5870s, nor is it sufficient for one 5970.
