Im building a PC i’m considering buying. Here are the specs:

-CPU: AMD Phenom™ X3 8400 Triple-Core CPU w/ HyperTransport Technology

-MOTHERBOARD: Asus M2N SLI NVIDIA nForce 560 SLI MCP Chipset DDR2/800 SATA RAID PCI-Express MBoard w/GbLAN, IEEE1394, USB2.0, &7.1Audio

-MEMORY: 2GB (2×1GB) PC6400 DDR2/800 Dual Channel Memory

-VIDEO CARD: NVIDIA GeForce 8500 GT 512MB 16X PCI Express

-HARD DRIVE: Single Hard Drive (250GB SATA-II 3.0Gb/s 8MB Cache 7200RPM HDD)

-Optical Drive: LG 20X DVD±R/±RW + CD-R/RW DRIVE DUAL LAYER

I know its not the best, but im going for affordable gaming equipment.
1.) Will this run todays games? (COD4, Gears of War, ETC.)
2.) Will it run "Tommorows" games, upcoming within the next year? (After one year i will buy new parts to upgrade it and take it to a computer store and have them install it…)
3.) Make any suggestions, im still new at this stuff.

First off, I would like to let you know, that I got this PC in the mail today and hooked all of the input/output devices like the mouse and monitor, and plugged it up…. Well, then after 10 minutes of being powered on I believe the PSU blew out. IT shut off and could not get it back on. Also , I was adjusting the power plug to the psu at the exact moment when this happened. I heard like a pop, and did smell a lil burning electrical smell. It was a 480 watt PSU… Which ibuypower has said that is more than suffiecent enough to power my computer, and suggested I not upgrade it, and just let them send me another one. I have a feeling that if that power supply burned out that fast, then this may happen again. IF not the same day , somewhere in the near future. Unless it was just faulty to begin with. But anyhow, I want to make sure that all of these components are compatible. I have a Quad Core Processor on a Phenom X2 and was beginning to think if that was not a good idea. Somebody who is really knowledgable on this topic, your answer would be greatly appreciated. Also, the PSU should be here tomorrow and I want to make sure I hook everything up the way it is. I know pretty much what needs to be powered. I just want to make sure that everything is hooked up properly and maybe a good site would help with that. Here is the system…. please let me know.

ok, well. I reviewed a video about installing a PSU. So it is pretty much as I suspected.
yea, thank you… I did actually get the 64 bit Windows VIsta Home. From Ibuypower. After reading other posts and talking to other people, I was able to determine that would be the best OS for my computer. I am just a lil concerned mainly with the PSU blowing out on the first 10 minutes of the computer being powered on.
