Phenom II X4?

965 is Overclocked version of 955BE but costs more.
It will be a wise decision to get a 955BE.

Question. How much ram do you need? 4 or 8gb?

http://www.newegg.com/Product/Prod [...] x%202GB%29 g.skill 2x 2GB ram. cost about $80 to $90.

If you need 8 gigs and have the Dimm slots to do it then double up on the ram above.

All those brands you've listed are good.Just make sure the one you buy is 1333Mhz(If DDR3).

For gaming or general purposes 4GB ram is enough.
So get only 4GB for now.
Get more if you feel the need.

It's ideal to select the RAM from the Qualified Vendors List (QVL) for your motherboard if it specifies it.ASUS for example has a QVL for their motherboards in which they test the RAM for compatibility.

^ Which mobo?

I forgot write this: mobo: gigabyte GA-MA790FXT-UD5P
thx

thx, that's right, but what about this ariticle

http://www.tweaktown.com/news/1138 [...] index.html

some person posts on anothers forums that there is chance for old c2 stepping processor amd 965 be is able to run with 4 ddr3 1333 but amd doesn't take resposible for this, new c3 stepping provides full ddr3 1333 support for 4 dimm.
so i my case i think it will work but bios downgrade the MHz to 1066 as is wrote in article above ...

Since you are new to this community I would like to suggest you to make new threads for each query.
If you start your own thread then you'll get better response.

What you do is go to the ASUS support website
http://support.asus.com/download/d [...] uage=en-us

Under General Download select motherboard under select product,Select Socket AM2/AM2+/AM3 under select series and then select your M4A785TD-V EVO under select models.A pop up will appear to select your operating system.Once selected it will show the downloads.
Click on the + sign under Qualified Vendors List It will show the M4A785TD-V EVO Memory QVL.Then download the file,be sure to save it and open it up.

The QVL memory could also be in your motherboards manual as well.
It will tell you everything that you need to know.

That just means the speed of the ram.

It's difficult to say exactly. US prices don't include taxes like VAT etc so when you say $190 it might look overly expensive.

It is yes, though the 955 BE is normally at a very similar price.

There is almost no difference between the 945, 955 and 965 Phenom II's that you cannot make up yourself with a little bit of overclocking.
