Am I in the right place? I need a new PC, I don't know anything and don't really want to learn. I thought I would just go to a local computer shop but I was insisted to come here.
I guess I want a middle of the road PC that can do some gaming and any moderate graphical upgrades from PS360 will be adequate.
Your Current Specs: Don't know but I recently put in extra rams so now I have 2.5 gigs.
Budget: $800, Canada
Main Use: Light Gaming?
General Usage: Web, word processing, skype, streaming to PS3 and I would like to be able to play video at 1080p. I also have a 5.1 sound system that I would like to keep using. Would also like to be able to burn CDs.
Monitor Resolution: I don't know. I currently have an HP 2159m and it seems ok.
List SPECIFIC games that you MUST be able to play: I'm so far removed from PC gaming that I don't even know. In general, I'd like to play at 60fps and medium settings I guess.
Looking to reuse any parts?: Mouse, monitor, router, printer, speaker system, external hard drives and that extra RAM I put in.
When will you build?: I can wait a month or two.
Will you be overclocking?: I prefer the 24hr display.
I guess that the "Enhanced" build in the OP is all you're looking for. About the RAM, we'd need more info but if you're talking about that little RAM I guess it's most likely DDR2 or even plain DDR so it wouldn't be compatible with a modern board. Besides, mix-matching RAM is usually not a good idea, and RAM nowadays is inexpensive.
If you're pretty pretty sure you're not overclocking right now go with the i3 3220 from the "Standard" build or get an i5 3450 (i3 = dual core, i5 = quad core) but get a Z77 mobo so you can upgrade later down the line maybe in 2-3 years and give new life to your PC. The final build would be more or less:
CPU: i3/i5
Mobo: your favorite Z77 board. Asrock Z77 Pro4 is a solid choice.
RAM: 8GB from the recommended in the OP
GPU: AMD HD 7850 2GB. My personal recommendation is a Sapphire, as their refrigeration is really good and silent in these cards
HDD: WD Blue as stated in the OP
PSU: Antec VP450 450W
Case: the one you like the most. Make sure it can fit an ATX-sized mobo
DVD: as stated in the OP
Sound Card: Xonar DG or Xonar DGX (only difference is the later using PCI-Express instead of PCI). This component is not mandatory but I guess you'll appreciate it if you're going to use a fancy 5.1 system.
There's no need for an aftermarket cooler if you're not overcloking so you can leave that for later. If there's some spare money after this, you can maybe check an SSD in addition to the HDD being the Samsung 830 or the Crucial M4 the best bang for your buck at 128GB.
