Hi! I know nothing about computers so that is why I decided to take on the task of building my own. Also, I am so tired of working on terrible computers that can not handle the work that I need to do. I figure if I build my own I will know how to upgrade if I ever need more functionality! If you could please give me any advice or opinions on my choices that would be great
I also am having trouble finding out the wattage for some of the parts so I just guessed at the wattage needed for my power supply. If it is too little or too much, please let me know.
The system as is equals to about $1,485.89
Needs to handle multiple browsers and several programs like Photoshop CS5, Illustrator CS5, and Dreamweaver 8 running at the same time.
Video Editing Software
Microsoft Office 2007
A couple of things I would change. First is the Mobo and Processor. Get the i5-2500k and a 1155 motherboard from Asus. The 2500k is faster and cheaper. That will save you about $100+ and use that savings to purchase a 128GB SSD for your operating system and programs. If you change to this, then the memory will be fine. if you are not overclocking though, 1333 would be adequate for your needs and a little cheaper.
The power supply you chose is great although I wondered why you linked it on the canadian site. Another option, instead of an SSD would be a second monitor. If you are going to do that much multitasking, 2 monitors will be a HUGE help.
You will undoubtedly get recommendations to switch to Sandy Bridge build, and if the goal is gaming, I'd echo that advice. However,with your listed programs, other than getting a CUDA capable card and very fast storage (SSD + HD suggested), I just haven't seen enough tests on SB with all of the programs on ya list to recommend strongly one way or the other.
I still feel there is no reason to go with the i7-950. The only "advantage" it has over the 2500k is hyperthreading. The chipset will be dead in 6 months and the motherboards are just as expensive as 1155 and don't offer anything that will be of value to ember as he is not gaming. Clock for clock, the 2500k is more efficient so in single threaded applications it will dominate. In threaded applications, it will at least keep pace with the 950 even if it looses a couple of benchmarks here and there. If you want hyper-threading get the i5-2600k which is only $35 more then the i7-950.
Also I don't see the need for an aftermarket cooler unless he will be overclocking a lot. A "mild" overclock to 4.2-4.5 will work on the stock cooler and he can save the cash.
