After all of your Help & guidance I will buy :
 
HDD 250 GB SATA II (8MB CACHE)     = $70.00
2 GB RAM DDR2                                   = $45.38
 
-
i mean for Video Editing purpose ONLY, No HD or Blu-Ray play backs.
ONLY for SD(no HD here also) DV Video Editing only.
 
so which will be better for faster rendering in "Adobe premier cs3" ??

My 1st priority is Video Editing. and games come much later. So plz help.

780G support a lot of stream decoding and the playback would be smooth. For the video editing, use a quad core, a phenom 9550 http://www.newegg.com/Product/Prod [...] 6819103251 or also, cheaper triple core http://www.newegg.com/Product/Prod [...] 6819103254
 
Don't forget the RAM. 2Gigs should be fine this one http://www.newegg.com/Product/Prod [...] 6820220174 had a MIR of 20$.

You already have a case, PSU, RAM, hard drives, keyboard, rodent, and any other peripherals?
With a budget of $280-$314 (estimated based on your post), AMD on a 780G chipset board will be your best choice, if only because the video chipset on that board will blow away the integrated Intel Graphics Media Deccelerator, and you really can't afford to get a replacement video card.
The quad core 9550 is $195; over your $180 price point, but within a $314 budget.  Even though that one is a quad core, this X2 5600+ might be a better choice: http://www.newegg.com/Product/Prod [...] 819103234.
Some of the 780G chipset boards can't really handle the 125W chips, especially if you overclock them.

Has everything you need includind OS. LAter you could drop a quad core in it.

Someone just did a review of the 780g chipset and darned if I can find it now but the result seemed to say that the CPU should be at or above 2.0 GHz for efficient decoding. I seem to recall that the processor they liked best was the newest "be" version. Sorry if I can't remember the specifics - just got back from the clinic from some spinal steriod injections so a little foggy but wanted to help.

Unless you are playing games or playing back hd content, you could easily get by with onboard graphics or a $30 video card. A fast video card wont accelerate video editing or encoding.

I will buy :
 
HDD 250 GB SATA II (8MB CACHE)     = $70.00
2 GB RAM DDR2                                   = $45.38

For the 125W support, take the Gigabyte mobo. The 9550 is 95W TDP.
 
The BE (replaced by the new and the same 4050e (2.1GHz), 4450e (2.3GHz) and 4850e (2.5GHz) but renumbered) series cost more but are rated 45W
 
You can wait for the 9100e, a 65W quad core but it will high priced, same as the 9550.
 
For the CPU speed above 2GHz for decoding, anantech and tom's have used a sempron 3000+, 1.6GHz. OK the CPU was loaded near 100% for HD decoding but the movie play smoothly...

Here's a couple of reviews:

 which AMD CPU should i buy Under $180???

GIGABYTE GA-MA78GM-S2H AM2+/AM2 AMD 780G HDMI Micro ATX AMD Motherboard - $90
http://www.newegg.com/Product/Prod [...] 6813128090
 
AMD Athlon 64 X2 5600+ Brisbane 2.9GHz Socket AM2 65W Dual-Core Processor Model ADO5600DOBOX - $124 w/ free shipping
http://www.newegg.com/Product/Prod [...] 6819103234
 
Stay away from Intel for your budget, you can get MUCH more going for AMD.

 
Actually the CPU requirement for smooth HD playback is minimal with this chipset. The review done here at Tom's, http://www.tomshardware.com/review [...] 785-3.html, showed that only a Sempron 3200+ (a 1.8GHz chip) was necessary for smooth playback at 1080p resolution.

The OP DOES NOT CARE ABOUT HD. he is not playing back hd content. He is just doing video editing of SD video.  
 
So all that Intergrated video on the chipsets means nada.  I would go for the E7200 and just give a slight overlock(fsb 1333) or even leave it at stock myself.
 
Or look at benchmarks that use the editing programs you will use and see what fits ya best. It may be faster clocked cheaper intel dual core, Maybe a AMD quad.
 
Basically get the fastest cpu for encoding you can afford. quads will most likely be the fastest then the higher clocked intels/amds.  
 
IMO not unless the AMD quads fall into your buget and peform well in the software you are going to use, I would steer clear of AMD all together for this build.

@ someguy7
Intel E7200 looks better than AMD in tests & nis also affordable for me.
 
What MoBo & VGa would you recommend for Intel E7200 processor?
-
My Major priority is Video editing.
later comes some games.

Just recently posted and got feedback on similar topic.  
 
I edit HDV and it seems that speed is way more important than L2 cache on cpus as far as video is concerned, because you're not throwing any surprises at the chip. Therefore some intels (i just bought an e2180) are really affordable for the speed. 'Playback' is irrelevant, even a p4 has enough juice for that.  
 
For SD you're only going to be "waiting" when you render color correction or other effects and output to Quicktime or whatever you export to. IMO 4 gigs of fast RAM is oh so worth it!

After all of your Help & guidance I will buy :
 
HDD 250 GB SATA II (8MB CACHE)     = $70.00

NOW Im Planing to Buy:

Intel Core 2 Duo E7200 ( i want to OverClock it)
   = $131.99
http://www.newegg.com/Product/Prod [...] &Tpk=e7200
-

Plz help me in these followings (Which Stuff to buy with the above CPU?):

- MotherBoard (OverClock able)
- VGA cheap & able to play some games

I would still side with an AMD system, personally for the following reasons:
 
1) Higher stock clock speed
2) Athlon X2s superior memory sub-system (higher bandwidth, faster access, which in a lot of cases is the determining factor for video encoding speed)
3) Superior onboard video with hardware-accelerated decoding (takes load off your CPU)
 
Having said that as my last AMD argument, if you're still wanting an Intel system here's my opinion on that:
 
Intel E7200 (9.5*266) overclocks to 3.8GHz - depending on sample - (9.5*400) before starting to overclock ram, which should be plenty fast enough - $132
 
Gigabyte EP35-DS3L - $90
http://www.newegg.com/Product/Prod [...] 6813128337
 
SAPPHIRE 100237L Radeon HD 3650 512MB 128-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - $62 after MIR
http://www.newegg.com/Product/Prod [...] 6814102725
 
and I would still go for 4GB of ram (regardless of OS), if it can fit into the budget:
Transcend 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model JM4GDDR2-8K - $72
http://www.newegg.com/Product/Prod [...] 6820208353
 
and I would change your HDD selection to this:
Western Digital Caviar SE16 WD3200AAKS 320GB 7200 RPM SATA 3.0Gb/s Hard Drive - $70
http://www.newegg.com/Product/Prod [...] 6822136074
It's the exact same price as the one you've listed before and is much faster and higher capacity.
 
If the things I've listed above are beyond your budget, you could scale back by getting a DDR2 version of the HD 3650 or a 2600Pro/XT.  Please trust me on the HDD, ram and motherboard selections, they are excellent choices.

ERROR:  "Budget" and "Video Editing" are not compatible goals.  Believe me, I've tried it.
 
That said:  For your purposes, you really ought to consider a quad of SOME sort.  A Q6600 or a Phenom 9550 for around $195.  I know that SSE4.1 offers tangible encoding improvements, but I don't know if SSE4a offers the same (I suspect not as much).  
 
If you're going to do any sort of capturing from analog sources, do yourself a favor and buy a second hard drive, maybe even a third for a simple RAID0.  Otherwise you'll probably find yourseld dropping a lot more frames than you'd care for.
