Deffo get yourself into Crossfire If your

but i want to know if those pieces are good for do what i want to do

Also, consider getting a cpu cooler if you going to overclock

I cant order from NewEgg cuz im outside of the USA Right now...i Born on NY but im at Dominican republic atm living here so i have no other choice...and about the DDR3 thing i want to spent that money because if in da future i wnat to change any piece like MEMORY TO ddr3 i will need to get a New MOBO know what i mean?

overclock from the bios or windows programs such as easy tuner both have their merits. I prefer from the bios but many others prefer the stability that the windows program grant. Always check your overclock with a program, I believe occt to be one of the best. It found a ram stick error in about 3 minutes and I never could catch on memtest provided I ran it for over 24 hours.

The performance difference between ddr2 and ddr3 is about 5% at most but you need to buy what you can justify. If you plan on keeping the ram then ddr3 is the choice for you

I would totally forget about that RAM, it will perform terrible.  The timings are so bad that I doubt that it will perform better than 533 Mhz DDR2 RAM.  Also I would DEFINITELY get this power supply instead:

That is one of the highest quality power supplies on the market, the one you linked is pretty bad.  When it comes to power supplies the quality of it is as important as the wattage and amperage.

Get that motherboard it supports DDR2 and DDR3.  Then get yourself some decent DDR2 800mhz RAM and you are set, the rest of the system is great!

Now forget DDR3
DDR3 will shine wiyh Nehalem wich is not 775 socket processor
There is no noticeabble increase in performance between DDR3 and DDR2 with 775 processors
you are spending more than 400$ for nothing
If you have the extra cash better to get another 4870
or go for QX9650 processor
Change ypur PSU to a better brand
Western Digital Caviar SE16 WD6400AAKS 640GB 7200 RPM 16MB Cache  is better than the one you picked
This combination is amazing and better than your selection
ASUS P5Q Deluxe LGA 775 Intel P45 Intel Motherboard                       210$ on newegg
mushkin 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500)  110$ on newegg

When you say overclocking, how much overclocking? Dynamic overclocking, sub-zero overclocking or what? If your looking at serious overclocking that setup is flawed, if your looking at a mild overclock I suggest you ensure the mobo/bios/ram situation has been sorted for you already because people are getting stuck with RAM.
 
"change any piece like MEMORY TO ddr3 i will need to get a New MOBO know what i mean? "
 
I don't know what you mean but I think your saying you want a mobo that will support at least 1333Mhz which most late model mainboards do anyhow. If you going to get ram for a high overclock I suggest going some Micron D9 ic's like Corsair DHX TWIN3X4096-1600C7DHXIN because with a locked multi your going to want to at least hit a 400Mhz FSB to give you 3.2Ghz unless you want a memory divider which you can then go some good ddr2-800Mhz
