Final Build List (Any good?)

Everything looks good except your RAM.

You want to buy in sets of 4GB for AM3. The 6GB RAM is setup for Core i7 (LGA 1366) builds. Here is the RAM I would recommend... http://www.newegg.com/Product/Prod [...] 6820231276

I'm running the same CPU on an ASUS M4A78T-E mobo with 6GB under Windows 7 - no problem whatsoever with using all of the RAM.

I run Premiere Pro a lot, often have numerous apps open, and am also regularly using W7's XP Mode, which eats quite a bit of memory. I think I got what I need, but thanks for worrying.

The single vs dual channel aspect seems pretty vague. There's lots of discussion on this forum and elsewhere. In theory, there should be a difference in performance. Practically, it seems there often is none, so whether this really matters remains unclear (at least to me).

But now u recommend me : G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model F3-10666CL7D-4GBRH - Retail
Dual Channel Intel Core i5 & Core i7 CPU for P55 motherboard that is also for Intelboard(p55)?

It can be used for any dual channel board, which could be either AMD or Intel. There isn't a specific tie from the CPU to the type of RAM, except through the motherboard. The motherboard you're choosing runs best with dual channel RAM, not triple channel. Plus, dual channel will be cheaper.

As stated by MadAdmiral, this RAM will work on the AM3 board. It states for Core i5 / i7 because it has equal to or below 1.65V for it's voltage requirements, which is required to run on the X58/P55 boards. Also at 1.5V, it gives you room to overclock easier with increases in voltage and still be within save level for motherboards.

All of it is used by Windows. With a few applications opened, I show about 4.6GB free. That drops (a lot) if I use certain Adobe apps.

I'm currently and will probably always use some variation on the Antec 300. I'm on my 3rd one so far (Nothing ever went wrong with them, I just give my old PCs away when I build a new one-- spending 100-170 more for a PSU/Case isn't a bad deal considering it saves my friends/family from spending 400+ on new PCs for their kids) and love them they are easy to mod, lots of air flow and good quality for the price. The only con I can think of with the 300 is the HDD attachment adding a few plastic/no-tool clips would be a nice improvement and relatively cheap, also some rubber/vibration absorbing material around where the HDDs attach isn't a bad idea either. But for the sub 70~ price you can't really beat it unless there is an uber sale on the 900. Also I buy the one without the LED fans on the front... I dislike bling.

Zip tying does work but I find it a bit annoying to have to reach inside my case to alter fanspeed . That's the only reason why I suggested the controller. Plus they do look cool.

Right now I'm running Outlook, Firefox, Photoshop, Soundbooth - all without any significant loads (no pic in PS, no audio file in SB). I started Captivate and published one of my projects - not my largest one. Mem dropped to 2407 at the lowest point (out of 6GB). That's without running Premiere, which I often do as well, and without XP Mode activated.

Convinced?

i read the article very interesting, but i orderd everything yesterday and instead of the G.Skill 1333mhz CL7 wich they didnt had and had to be ordered with a 20 day waiting time i have chosen the OCZ Gold Edition 4 GB, PC3-12800, 1600 MHz, 8, Kit Of 2...
and the 4Gb will definitely be enough cus i don't work with many/big programs at the same time maybe someday i will OC and it will come in handy the 1600mhz
